to see a person of the same sex and wonder what it would be to make out with her or him (if you are a guy). To wonder what it would feel like to touch her body all over.......and stuff like that?

lol no, it's called curiosity
its just letting ur imagination roam

if you were on a sleep over with that person in bed together and they started something, would you let them? Help them? Remain passive? Or tell them to stop?

What you're describing is completely normal for anyone really. The human mind has a way of 'wondering what if?'.... we are highly curious creatures after all So yes, thinking about people of the same-sex in a sexual manner is completely natural, just don't ever act on those thoughts and you'll be fine (Only because you found them irregular, and so clearly you are not a homosexual. This is often one of the most common mistakes people make. They have a thought such as this, and suddenly they think they're homosexual! Incorrect. If you find these thoughts normal and not irregular, then you are truly homosexual, otherwise they are just the human mind being curious. *Hope this was clear enough to understand*)

And in answer to the above, it cannot be said any action would be taken for definite; in the real situation... anything really could happen, it depends.
