I'm not bisexual, but from my point of view you should not worry to much, in this days people are more open to accept the sexuality of other people. Yeah, some people may raise an eyebrow, and some others look shocked at the beginning when you tell them, but your true friends will accept you
and stand by your side regardless of your sexual preference, because they will understand that you are the same nice person.
If you take some time to read, you will find that there are many bi people here in the forum, and they all enjoy sex the same way as any other people.
Well i hope they can give you a better answer. C ya
by the way, have you seen a movie called "Kissing Jessica Stain"?.
