I think in general, women are glad when your penis is finally in their vagina. They've already decided to sleep with you. By the time they've let you get that far, you're in - so now it's time to be on point and rock her world. Be honored to be invited regardless of your size. Be a man, focus on her, and make the most of it.
Be her best, not her biggest.
This sums it all, and after that it's all related to what both camps are after, i think that's it's retarded and naive to build relationships on boobs and dicks size... am not sure i'd enjoy sex with someone so narrow minded and with such a 2D vision.
and then of course there's sex for sex, this is fun, till your tricks no longer works, deflated boobs, aging body, etc...where you're no longer interesting in that futility hunt...
you can fuck or make love, by nature we can all fuck, but being able to make love ain't that easy... that's where, regardless of your cock size, you'll be dropped, just because you're maybe cool & fun but not IT.
and for some i'd say don't impersonate porn actors, this kind of sex, is what masturbation is to real intercourse.
as Olderguy said it so well : Be her best, not her biggest.
