I am a 25 year old male. I am scared of turning into a gay or homosexual. In the past, I had senseless and intrusive images popping in my head that I am kissing a guy whenever I used to be with my male friends. I never felt an attraction towards any guy. It happened six years before, but never thought about the reason. This thing stopped when I asked about this issue to a doctor and he said it as OCD. Everything was fine for over six to seven months. But, when I over think about why I am getting those images in my mind then the thing gets worse. I check every time when I see a guy whether I am attracted to him or not. Indeed, it sounds like I have gone mad. In my office there is a guy who is very attractive. But, when I fantasize him just to check whether I am normal or turning into a gay, I feel weird. But, I cannot stop myself looking at him. I envy him too, because I always wanted personality, health and voice like him. Whenever I see him I feel something different as if I am looking a girl. I am scared now. Please help.
