[The penis or brains cause in the meantime 3 more posts appeared LOL!] It`s too difficult cause...I`ll explain: if you chose brains, it means you didn`t chose penis which means you preffer having brains but a small dick which is not good. Yes, being intelligent can attract people but when you get in bed? They`ll just laugh at you
If instead you chose penis, it means you don`t want brain and even if you might have some sexual experiences with people interested in big cocks, brains also matters...noone would want to date a less intelligent person...a dumb one let`s say... and you cannot live only by having sex with your big penis LOL!
So, it`s either both or...I won`t chose
