Why more girls are attracted to me, compared to guys?

My friends and I are really freaked out by this 'cause wheneva we went to clubs, some girls approached me for a dance and my friends' gfs insisted on dancing with me when they're drunk. If it's just once, it wouldn't surprise me but it always happens. Whenever my close girlfriends are drunk, they'd try to stick around me and try to kiss me! Why is that so? I gotta admit that I feel more comfortable dancing/being wif girls too and sometimes I fantasize girls as much as guys. Could it be that I'm a Bi? But I dun think I'd want to have a relationship with a girl though. Never thought of it. Help me!
