How do you know wheather i am gay?

Most guys figure it out at some point. Depending on your age, it could just be you developing and being curious. If past 18 or so and you are asking yourself the question, there must be something that is causing you to ask. A pretty good way of finding out is to look at what you think about while masturbating. What you think about for stimulation when you are only trying to please yourself is a good indicator of which team you are on. Whatever your orientation, it is how you were meant to be and has to be alright. We are all raised with the assumption that we are straight and for some, that just isn't true. This can make us change how we see ourselves, but there's nothing wrong with that.
