The male surely... As the female won't have anything to put it on... Where were you in sex education lol
I say "Do you wanna fuck me?" He says "Damn right I do!" I give him a condom he puts it on and we fuck .... simples!!
Why surely the guy's gonna put it on...and as a guy I'd put one on for a guy if it helped things to go more smoothly....I reckon the only exceptions would be where a partner prefers to handle the guys cock, or more likely....wants to make sure the damned things on and fitted properly.
I`ve tried putting condoms on (not on myself i hasten to add)but I find it so fiddly, I`m hopeless at it, thankfully we don`t need to use them anymore
