personaly
i find that if a bloke ask's a woman if shes bi and she says yes they think thats cool (for a hetro bloke theres only one thing better than 1 woman and thats 2) if she says no its like why not.
if a bloke was to admit to being bi, they will just say he's completly gay and trying to deniy it in some way.
i hate labels why why why as long as your happy and not forcing anyone its no one else's business.
if group situation turned up who could honistly say 100%
