Seems that I need to make a few explanations:
-First of all regarding monogamy. Well, why should it be different for me than any straight married man? Don't tell me that no straight married man ever feels sexually attracted towards a woman other than his wife. The choice is then his. The only difference in my case is that if I ever do get married I can become sexually attracted to a woman or
man, but other than that it's just the same thing. Get my point? Sexuality has nothing to do with being faithful or unfaithful.
-As regards religion. I was given religious freedom by my parents (who are agnostic) and I had been brought up at a Catholic primary school. Two or so years ago, though, I somehow distanced myself from Catholic faith and became more or less of an agnostic myself. Now my rejection of Catholicism comes stronger than ever before - how can I possibly be Catholic if the Church offers no tolerance to people who are not straight?
-To Shawn Patrick: before, I didn't ever admit to myself that I should be anything else than straight, it didn't even cross my mind. As an obvious result, I was scared of and uncomfortable with my attraction for members of the male gender. Now, having talked it over with people, I realized that I'm not entirely straight and came to accept that I am bisexual. Basically the reason for this switch was talking about it and gaining more self-esteem and courage. As I said, that's mostly the merit of a fellow member who I first mentioned my feelings to (Remember that big hug I wanted to give you? Well, you're gonna get it one day when we meet in person
-The last point is that no, not everyone is bisexual. It's not a question of 'equipment', it's a question of feelings and attraction. In the case of most men, attraction towards other males is just not there so they're not bisexual. In my case it is
there, but so is an attraction towards females. That makes my sexuality pretty obvious.
Thanks for the feedback to everyone!
