I just wanna know to keep a look out on guys who like me and who like my p***y
Well, a guy having a boner doesn't necessarily mean he likes you. Guys get boners for all kinds of reasons or for no reason at all. And, a guy might still like you even if he doesn't get an automatic boner... Anyway, there isn't really any way to tell unless you just ask the guy. :)
Sometimes it means he likes my tits Mus p***y my ass or all 3
