I am kinda curious about something related to sexuality

I would say average or slightly longer/thicker than average is most pleasurable. Too small and you barely even feel him and won’t climax. Way too large and it just hurts, especially if he doesn’t take extreme care to be slow and gentle. I’m biased because I climax regularly from PIV, but I feel like the responsibility is heavily on the man to have the right equipment and skills to make a woman finish from PIV - I do think most women are capable of it, and a man is a major disappointment if he can’t do that.

For me girth matters more than length but in the sense that too thick really hurts for me because it irritates my urethral opening in basically all positions no matter how wet I am, if we are using lube or how much foreplay there has been. Maybe my anatomy is just weird in that sense.

My "perfect" choice would probably be 5,5-6,5 inches with no more than average girth.

EDIT: No idea why this is getting downvoted... it's my personal experience, and other women will obviously feel differently.

But here's another thought: Wouldn't a bigger penis be an evolutionary advantage, too, because being able to penetrate deeper means the sperm has a shorter way to travel? I also know that the clitoris extends inwards quite a bit and the part we see on the outside is literally just "the tip of the iceberg". A bigger penis is probably able to reach places and provide stimulation from inside that a smaller one can't.

I've only ever had PIV with one man and I felt his dick was actually a bit too large for me. It wasn't extremely enormous but I have a small frame, and it always felt like it was making me sore, and he often hit my cervix which is super uncomfortable. We had to do angles where he couldn't go in all the way so it didn't hurt. Even then, it wasn't the most fun thing in the world. Some of that also had to do with his general impatience and dismissiveness, so it wasn't just the dick. But that experience taught me that bigger isn't always better.

I can come from penetration alone, but the size of the dick matters a LOT. If it’s too small, I feel nothing. Too big and it HURTS like hell.

I think this is an equipment issue, not an actual truth that women can’t come from PIV sex alone. You do have to find a compatible partner in order to have that experience tho.

It absolutely makes a difference. Anything under 5 inches might "feel nice" because you're close physically with your man, the sensation of hot physical intimacy but you aren't going to get vaginal orgasms from a 4 incher unless he's super girthy but even then, most women don't have extremely shallow vaginas (some do though, they vary). On the flip side, anything over 7 inches can be painful. Even with lube, it will make you sore which is a huge letdown to have to wait for your burning puffy vagina (from all the friction) to cool off. I like a man with a "thicker" penis... Ie not skinny... That feels terrible and boring at any length .. between 5 and 7 inches. That's pretty common, I would say of the twenty five men I've slept with or been physical, 60% have penis around 5 inches, 25% have 7 inch plus, and 20% have 4inchers.

My ex had maybe 5 inches and it felt nice to be close to him, at certain angles it was quite pleasurable, but he only made me straight up orgasm with his fingers. The curvature of the penis slightly upward also affects whether it's stimulating your g spot. 7 plus inches can also ram your cervix which is not pleasant.

I've literally never not orgasmed from PIV (well, I tend to forget the 4 inch experiences lmaoo) besides my ex. He was selfish- understand any man who doesn't want to wear condoms is going to be selfish in many ways including your pleasure. Not worth the risk, ALWAYS use condoms.

Ladies look up the A spot and areas around the cervix, gentle pressure on those is great to achieve vaginal orgasm. Also make sure you have some warm up before penetration.

Also taking it at YOUR pace not his and "squeezing" to what feels best. Above all Comfort with the partner, which is a real problem in our society as these men are 🗑️

Some women can orgasm from PIV, some cannot, no matter the skill or size of the man. I think it's hard to generalize on this one.

For me, size matters mostly for visual purposes. I feel pity and sadness when I see a micropenis. No amount of propaganda/conditioning can make feel otherwise, so if I see a tiny penis, I will just not be interested.

I've never orgasmed from PIV (been with 18guys, married twice, one child).

I've tried the lovense lush, which stimulates the g-spot and other vibrators and dildos, nothing worked. I just don't seem to have a spot in there that gets me even close. I did read, that if you're aroused, your clit shows more and the penis doesn't or barely stimulates it from penetration alone, because it doesn't touch it (and yes, I'm aware a huge part of the clit lays inside).

So the only thing with a guy that actually gets me off is his hand or maybe oral, if he's really good.

Edited to add, I do get multiple (20+) orgasms when I use my hand on clit. So it's not like I can't orgasm at all, it's just a dick alone doesn't do it for me it seems.

Incels gonna lose their mind over this one like that post you're referencing 😂

all i can say is if its too small it's not doing anything at all

It totally depends on my mood. I’ve orgasmed from my ex husband way too big penis, my ex boyfriend way too small penis and my current husband’s jus right penis.

The penis size doesn’t seem to make a difference to me, but my emotional state absolutely does.

Never orgasmed from PIV but dick size absolutely matters to me. I’m a size queen for sure and consider anything smaller than 15 cm small and unpleasurable. I’ve slept with men with 20 cm penises and it was never ever too big for me. The bigger it is, the better it feels.

Btw I’m pretty certain about my metrics - I straight up whip out my trusty sewing ruler sometime before sex and see for myself.

I’m kinda in the same boat as you where I’m unsure if this is true but don’t have the experience to know. I’ve only been with one man and his penis was pretty big and I was in pain pretty often but he definitely wasn’t doing anything right and I also have a retroverted uterus.

from what i’ve experienced, female orgasm can occur during penetration ONLY if her clit is also being stimulated; i.e., if he is on top and pressing down on her, while penetrating. otherwise PIV is just another step in arousal, it stimulates the epinephrine/norepinephrine pulsatility.

Your clitoris extends inside your body and down the sides of your vulva. "PIV alone" doesn't mean it's not part of the orgasm experience, it's just not necessarily going to push you over the edge. Just like getting your nipples stimulated isn't going to make you orgasm but it may be critical to getting to orgasm.

I've had penetration get me to 99% and a slight touch to the clit was all I needed to have an orgasm. But keep in mind that penetration also stimulates your clitoris as your bodies rub together, you are rubbed inside, and girth spreads your lips open. It's a whole experience.

Okay phew it's hot in here 🔥

I’d say 6.5-7.5 works best for me, with proportional girth. I agree with the woman who said PIV orgasms happen in positions like missionary or cowgirl where my clit at least gets a little something. Otherwise it’ll get like 80-90% there and I need a couple seconds of fingers on clit to get it over the edge.

Of my sample size of 18 most were in that range. 2 were like 5 and 2 were like 8/8.5. So the comfy range feels like a very reasonable standard/preference.

It also has never worked with a dildo. It’s just different when there’s a man behind the penis. Less mechanical thrusting maybe? The density or texture? My arm’s power vs male hip power?

Interestingly, when I’m alone I can meditate and kegels myself to orgasm. That was friggin fun to figure out, but is also a good tool to have during sex to be able to be in that meditative space a little bit. More orgasms easier, and overall good for not being in my head.

I can orgasm from PIV with my husband. Doesn’t always happen, but it’s a nice surprise.

Only ever happened ONCE before with one other guy a long time ago.

What is the post you are referencing?

I think most women can orgasm through penetrative sex that is focused on stimulating her clit.

I have vaginismus and rarely attempt PIV, but in the past, I could consistently orgasm through PIV when I'm on top. I'd either lean forward or have him sit up to put more pressure against my clit. He'd stay relatively still while I rub my clit against him until I orgasm. The orgasm mostly comes from the external stimulation that's under my control, but the penis exerts pressure from the inside too.

I've been able to orgasm with most partners if I'm on top, so I don't care about size unless it's so tiny I can barely feel it (that's only happened once because it was the size of a thumb).

I find it easier to orgasm when the man's intact. Circumcised men tend to have less sensitivity, and the circumcised penis tends to be uncomfortably hard with little give.
