I’m at a size where I get “you are pretty big” frequently (not always, but frequently enough) .. probably a combination of length+circumference because I’m not that lengthy (yet).
I have never had any women who dismissed sex for that reason initially, but I’ve had women dismiss sex after the “first session” because they gotten sore.
So I have wondered why the hell I keep pushing.
I think the simple reason is because I can (improve myself).. that is the biggest motivator.
I do training and sports similarly, not because I’ll ever beat any world record, but because I will continue to improve just a bit every time.
I’ve told my self I definitely will stop at 20cm..
