Please don't double post. THX.
Anyways, I have thoughts about experimenting with my friends, and its just a phase, a stage referred to as curiosity. You wanna compare, so you know the "average" for your age, you want to prove your more of a "man". Remember, they're just thoughts, and as you said, you find them repulsive, well if you find them repulsive, chances are you're not gay. I'd say 90% of all guys get these thoughts/dreams during puberty. You're perfectly normal, and as long as you find experimenting with guys repulsive, and you believe you're sexually attracted to girls, you're probably straight, but only time will tell.

I'm way too tired, I've tried
I'm fired up and ready to roll
