I’d agree with 7.6” BPEL x 5.6” EG
I know that many average-sized women really love the feeling of being stretching by 3 fingers - a level of stretch my cock doesn’t provide at 5”, but I imagine it would come pretty close to a perfect stretch at 5.6”. And I know that by depth, my 6” often leaves more room for penetration (though not always!). I personally have no desire to toy around with the possibly of banging cervixes, so I don’t know how long is perfect - I’d say another 1.25 - 1.5”. I’ve had partners with shallow cunts and it’s just not fun. Hitting cervix sucks because it basically puts her on edge (and not in a good way).
It really depends on the woman. If we’re talking the average lay, I think most can be satisfied by an average dick. Is that the perfect dick? How can you even say?
Now, from a different approach, the only parallel I can draw, and it’s not perfect, is the question “what is the perfect tightness of a cunt?” Let’s say there’s an average tightness. That means many women are also tighter than average - by definition about 50% ought to be average or tighter. Are they better vaginas? Are some of them more perfect? Who can say? It depends on who’s judging. Same applies to cocks. But in my case, I’d say my perfect tightness is *slightly tight and consistently that way* - meaning, doesn’t change size much. For a woman this may be “slightly larger than average and consistently that way” - meaning, stays hard.
Remember, there’s more to your cock than its size. Its performance, warmth, texture, shape, etc. All affect the woman, same way her wetness, warmth, texture, shape, willingness, etc. All affect your experience.
I have had partners who are *extremely* tight but couldn’t get off from penetration. I will never forget that incredible feeling of an extremely tight vagina squeezing my dick. But I wouldn’t fuck her more than once a year or so. Because I don’t like how she fucks or the human that is attached to her vagina. My current partner can take a fist and then have multiple O’s from PIV (and still feels great). It’s honestly not as memorable as a tighter vagina, so really the reason I want to grow my size is so that more vaginas will feel that tight *for me* - a woman’s pleasure potential doesn’t necessarily correlate with your cock size though. The proof is in my example. An extremely tight vagina that couldn’t have orgasms, versus a vagina that can accommodate many different sizes and orgasm repeatedly all the same. Am I satisfied that I can make my partner cum a lot? Yes. But I want her to *feel* more memorable to me.
But am I going to dump my fist-eating lover for a tighter lover? Never. The sex is satisfying, frequent, and she’s my favorite person in the world at the moment.
On top of that, I couldn’t last more than 5 - 10 minutes with the tight girl, ever. My dick also got sore easily and I couldn’t have sex as often. So, tight vaginas - are they the best? Well, they feel great. But, lesson learned - prefer a slightly looser vagina. Consider that a woman might also have a similar experience - yes, a big cock fills her up, stimulates her nerves like crazy, makes her cum quickly.. But there’s a downside. She’s sore, she can’t have as much sex as she wants, and she can’t take the dick for as long as she’d like. Eventually, she decides that smaller than huge is her preferred perfect penis size.
Then there are vaginas that are larger than average. Anywhere from “kinda loose” to “cavernous.” As someone with an average cock, I find the 50% or so of women who lean toward the looser side of things to not be good lays for me. But things get more complicated, because the two loosest women I’ve ever slept with also found having a cock inside of them extremely painful and uncomfortable. A truly confusing thing if you equate penis-to-vagina size ratio as the standard for whether there’s going to be good sex or not. But fortunately it doesn’t work that way. Welcome to the mystery. You will never know what the perfect penis size is. Unless of course you’re strictly after the sensations of pleasure that sex gives - but I’ve found that as an adult this is no longer what matters in sex or a relationship. Thinking of sex as nothing but penis on vaginal friction is frankly ridiculous! That’s not the source of attachments, love, or even great sex. Great sensations, yes. Great sex, no.
I think the best size penis is the size you feel happy with, and which satisfies 50% of your partners enough to keep them interested in you. If you’re too big, you’ll miss out on enjoying the women who can’t comfortably accommodate your penis. The percentage will likely remain around 50%. I mean, if you’ve ever been to reddit’s BDP page, you’ll know what I’m talking about. Many hung dudes either don’t get to fuck women of their choice because they don’t want something their size inside of them, or their sex frequently ends in crying, bleeding, and frustration.
If I go by my own standard of “slightly tighter than average and consistent in size over various states of arousal,” then the perfect penis size would be “slightly larger than average with great EQ.” But like I’ve stated, size and sexual satisfaction are clearly overcorrelated in our minds as men. There are loose women who can’t take a medium cock due to pain. There are tight women who can’t get off to a perfect cock because the nerves in her vagina or the chemistry of her brain restrict her O-potential. The missing ingredients in our thinking here are, in my opinion, the incredible complexity and diversity of female vaginal nerve plexuses and hormones.
In other words, it is truly a mystery. Tight fits that don’t get off, loose fits that find sex painful, stretchy fits that cum multiple times. I want a bigger dick because big dick porn has made me aesthetically in love with the sight of big dicks. I want something big in my pants because it makes me feel more secure, not because there’s some magical size answer to our sexual problems. All that said, the answer is of course, slightly larger than what you have, because that’s what boosts your confidence and performance in the bedroom, and I think we all deserve to feel our best when we fuck. If only we could achieve that confidence first and then share our bigger dicks as a bonus.
