I'm happy with who I am. And that has barely anything to do with my sexual prefernce. I guess I just regret the way I handled it when I was younger.
I wish sometimes I wasn't bi as it makes your life a lot more complicated and difficult in many ways. Not being sexually satisfied with just a partner of one sex for example.
It was a long journey to have total acceptance of my sexuality. I had internalized homophobia, for a long time. By the time I reached my mid -20's, I had a wonderful support system of bi/gay/lesbian friends. I began to accept myself. Looking back I would not change a thing. Being gay is who I am. I am completely and happy and comfortable with the person that I am.
