i've always thought that i'm not straight, whether because i liked girls completely, or because i like guys as well. now, more and more, i'm led to believe that i'm not straight, and not even bisexual, but full on lesbian. however, i still get aroused at the thought of being with a man, and i've never been with either before (i'm young, so y'know...) but i'm eager to figure this all out and be concrete in it. i'm thinking about asking a friend to, well, experiment with, and then see where it goes from there, but this would be a guy. i'm still really nervous and worried that this might be a mistake. has anyone else had this experience?
