I had a bottom friend of mine so turned on by our making out, he asked if he could top me - he’s average small, curved and hard as a rock when Im deep inside him- a bit surprised , I said sure! He said he hadn’t topped in years, making apologetic noises ahead of positioning himself. I took control, pulled my thighs back, and said, “Fuck your daddy, fuck me like you want me to fuck you, you hard horny fucker! ” He pushed in and fucked me so good, I never knew 4.5” could hit me right, but feeling his intensity and lust (and that curve!) had me cumming in no time, and he unloaded hard, and colapsed on me and smiled like he was drunk as we kissed and dozed.
So size matters to some, its their thing, but for many if not most, desire lust passion and intensity and even sexual tension make fucking and love making exciting.
