Might make a mistake

[Atonement]

Okay, I used to have myself convinced that I was gay, now I am second guessing it and hardly believing it. I am afraid to act on any feelings because if I was to come out to people and then feel straight, the what would I do? I am afraid of making a mistake... :confused:

don't come out to anyone yet. wait until you're ready. you're not now because you're confused. which is totally ok for someone your age :D don't feel bad. this type of thing can take time.

you could be bisexual my advice is just wait till your 100% sure

Sexuality can be a very confusing issue during your teenage years, and you shouldn't label yourself (gay, bisexual, straight, bi-curious) or come out to anyone unless you are absolutely certain yourself. You need to consider your emotional and physical attractions to both genders and just sit down, take some time and have a think about it.
Good luck. :)
