'Maybe I'm a selfish, shallow moo but I couldn't settle for someone who didn't satisfy me sexually just cos he was nice. Unless you're a really special kind of a person (and I'm not ) then putting up with crap sex, particularly early on in a relationship when it's supposed to be great, just can't be sustainable in the longer term whatever other great qualities the bloke might have.'
Nail hitting head.
And that goes not just for cock size, but also men who won't give or receive oral, because I love both, who are only interested in sex in a bed in one position (no spontaneity), men who want to swing, want butt sex, etc.
A whole host of things that means we won't be sexually compatible, and yes, for me, small willy is on that list.
Different situation if a person physically changes over time and isn't able to go out the way we did when we first got together and spent days in bed, couldn't wait to get each other's clothes off, etc.
But at the very beginning of a relationship? Yeah, for me, sex is really important, penetration by him and orgasm from that, both mine and his, is important to me and so I sought men who felt the same.
Plenty of nice ones out there with whom you might be more compatible.
Life is too short to court bad sex, IMO.
