Uhhhh I've been having sex like things in my head I have these pictures of guys kissing more fantasies of guys for the past month and they are nonstop and I was just wondering if there was a way to get rid of them cause I can't think of girls as much anymore and I really find it annoying and irritating?

Oh and I'm a male 15

We have been over this many times. Maybe you should start to consider that this might be something you want to look into further.

Perhaps you do prefer guys. This is something you have to sort out. Oliver said in an earlier post that he knew when he was younger, but I think there are plenty of guys who struggle with it into their teens and beyond. Some just can't admit it. Some do just fine with women for years, through marriage and children, before 'discovering' that they are just more attracted to men. If this is torturing you, back off one on one relationships for a few years.
Some people are bi while others say there is no such thing. Other people say they are gay and straight serially, depending on who they are in love with at the moment. Plenty of gay men have very deep relationships with women and get as upset over losing them as they do with any lover. The world is full of infinite variety.

You are fortunate to have understanding parents! Be glad of that.

I want to add one more thing. If through your life's journey you come to terms with this and it turns out that you are gay, you will be fine. But remember, being gay doesn't mean the only thing you are is gay. You will be many things and being gay might just be a small part of it. If it turns out that you are complete heterosexual, you will be fine as well. Embrace who you are and by all means have fun with it!
