Why have I started fantasizing about women when I've only ever liked men?

I have always been attracted to men, and have only been with men. I am currently happily engaged to a man, and have no doubts about our relationship. However, I've discovered over the past couple of years (even when I was with my previous boyfriend) that I do not like porn with men in it. I like lesbian porn! And anytime I've masturbated I've fantasized about women (never one that I know or have seen.) It's made me very uncomfortable, finally admitting it to myself. I do remember when I was in 7th grade there was a new girl at our school. When she got a boyfriend I was very jealous; I just assumed it was because she was new and I didn't have all her attention *ha* Is this normal? Am I out of my mind!?


What are the common reasons for condom failure?

I live in Prague, Czech Republic — Europe. Before asking any question, I should tell you that I really appreciate your service. As for my question, I would like to ask you about the most common reasons for condom failure as a contraceptive method. I suppose that the most frequent one is condom breakage. But what are the others? I am especially concerned about pregnancy risk implied by the accidental transfer of sperm in pre-cum to condom by fingers while putting it on.
