It's ok to be Bisexual or even Homosexual. It's a hard thing to contend with and accept but at the end of the day, if you can be completely honest with youself and others then you will be much happier. It's a scary thing to think of, homosexuality is stigmatized and is usually met with negative reactions from friends and family but mostly it comes from within. It's a complete shift in your reality and people are afraid to let go of their ego's, their perception of self that they want to hold on to, the one they believe the people they care about have come to accept, the self that you and everyone around you "knows" and accepts.
If you enjoy sex with men, sucking on a penis then that is absolutely homosexual. You can still be into woman, you can be into woman and men or even if you are just into men, that is ok. It's completely fine and if you get negative reactions from friends and family because of it, you can't own that, their reaction to it is theirs and theirs alone. Just focus on allowing youself to accept it and don't hate yourself for it. It's something that has to be accepted or it could lead to you destroying yourself.
