Well, first off. I'm 21 and female. I'm pretty sure I'm bi but I'm questioning it right now. When I was 15 I realized that the "Spice Girls" were really hot and sexy. So, than I assumed that I was lesbian. But I realized that I still thought guys were cute and hot. And when I got into high school I could imagine myself in sexual situations with girls but when I tried to imagine with guys I felt embarresed. To this day I still feel embaressed when I think of sexual situations with guys. But not with girls. But I still get a tingle when I walk past a guy. Am I bi or lesbian? I have no idea right now.
you are just a person who needs to discover and become one with your sexuality. Be it with men, women or both. try this site www.sexuality.org it is a wonderful resource.
Being bisexual doubles your chance for dating...I have been bisexual since my senior year in high school and I do not regret it for one second...go both ways. I also have been pleased to date three women who were also bisexual and two of them actually liked to see me with another man. I just say go with the flow and how you feel at the moment! Best of luck!
