My thoughts, a man who has had a lot of sex with women and also seen a lot of penises in real life…
(1) most people (whether man or woman) are completely fine and happy to have sex with an average or even below average penis
(2) most people (whether man or woman) find large penises erotic, aesthetically pleasing, etc
(3) the average penis size is actually larger than what studies say… If and only if for the simple reason that guys with massive penises aren’t all that rare and any one who has had sex with more than a few guys is likely to have come across one
(4) if a woman has orgasmed before, she can probably orgasm on a penis of nearly any size, given the right connection and arousal
(5) if a woman has never orgasmed before, she might be able to orgasm for the first time if she tries a bigger penis
