I’m with djrobins. The average female’s vagina is about 4 inches and can expand upwards to on average 8 inches. And like penis sizes, I’m sure vagina sizes vary also as to length & thickness they can handle. So it seems to me that 8 inches in length is an optimum goal for the average woman. If you’re married to a woman that has above average vaginal length, and would appreciate longer than 8”, then I could see why an acknowledging husband (or committed boyfriend) might want to shoot for 9”s.
Most woman, if given the choice, seem to prefer girth first, then length. The vaginal walls are flexible and can expand appreciably to fit most men’s thickness (eventually). Seems that many women like the feel of thickness because it stimulates the vaginal walls more so, and a thick penis may actually tug on the clitoris during sex, amplifying the pleasure. Now I’m sure every woman has different preferences, which makes it difficult to know what the majority of women’s preferences are for optimal penis size. That being said, it appears that the polls, if accurate, suggest that women prefer an above average penis over a below average penis, optimally speaking, 7-8 inches. This is why IMHO I think shooting for approx 8” length makes sense to me.
However, I must qualify that although some women can quantify the length they prefer (some haven’t a clue), but I can’t find any polls whereby they show any accuracy in quantifying girth in inches. Here lies the conundrum. They can use their hands to visually show what they like, but how can they extrapolate that into actual inches onto a poll? So my theory is they have a much better ability to visualize & quantify their preferred length (+ or - an inch for many women), but I don’t think they have a clue how to quantify girth measurements. Plus, some women don’t know the difference between Diameter & Circumference. Sorry for rambling on here, but I’m more perplexed as to what would be the perfect girth measurement to shoot for. I’m thinking about 6 inches, but wonder if 6.5 - 7 inches wouldn’t be more preferable for the masses of women, if they had a choice. I’m guessing that anything above 7 inches is just going to be too uncomfortable for most women., and the goal for us men is to give women the greatest pleasure, and multiple orgasms. BUT then I look at the other extreme, that if the average man’s girth is around 4.5 - 5.2”, why would God create man with girth that isn’t optimal for women’s pleasure? LOL. I mean really!
