I'm confused, please help?

Hi, i'm a 16 year old male.For the past year and a half or so, i've been slowly getting more and more same- dreams/fantasies (They've been getting more intense, too), and finding the opposite less and less attractive(Even if I try to have fantasys about the opposite , it doesn't "Turn me on") but for the last four months or so, I don't find the opposite interesting at all, and all of my fantasies are of the same . I liked girls up until a year ago, but now no girls really intrest me, and can only think of same- thins. The opposite sex doesn't even "Turn me on" anymore. I've started looking at the same sex, and am seeming drawn to look at guys "area". I feel like i'd be more comfortable snuggling/hugging up on someone of the same sex. If I am gay, how can I accept it?
