I have been thinking back to when I hit puberty. I can clearly remember having strong sexual desires for males. Most of those were boys in my year at school. Prior to this period I only had an interest in girls. But during this time I assumed I was gay, as I only became aroused when I thought about men. These feelings lasted for probably around a year and as if overnight I returned to becoming attracted to women. I have felt this way ever since. However, if I see a clip of a guy being examined by a doctor, I sometimes get that feeling back. Is this normal, are there any other guys out there who felt the same growing up?
