Sounds like your psychotherapist knows what he is talking about. I doubt you are gay or even bisexual but all these psychological problems you have are confusing you. Also, stay away from porn. Porn is a very distorted perception of what sex is supposed to be like. Men don't have huge penises like that, and it very objectifies women in a violent way. Also, body hair and facial hair are no indication of whether you are fertile or not, chances are you are perfectly healthy but have spent a great deal of time worrying because the society you grew up in is so restricted and misinformed.
