What should I do about these two guys?

Just saying, I really have no experience with this sort of thing, and I’m just looking for some advice.

There are these two guys that I think I might fancy, but I have no idea what I should do.

I met Boy A last year in a class we had together. We had the last part of this class together this year, and developed feelings for each other. We had one study date where we both admitted we liked one another. He, however, doesn’t date because he’s afraid of all the obligations (walking to class, making dates, etc) and I had said that I wouldn’t make him do a lot, and then changed the subject. The term ended, however, and we haven’t had much of a chance to speak with each other. I do like him a lot, though, and have had plans to ask him out again just to see where it’s going (if anything will happen).

Then, a friend of mine told me that her friend, Boy B, who goes to a different school, saw me in the play and was interested. I was curious, and started talking to him. He was pretty interested, asking me if I was single, and we both flirted quite a bit.

I can’t help but feel a bit guilty. Maybe because I still like Boy A, even though I think I might be developing feelings for Boy B, and I don’t want to hurt feelings. I know I shouldn’t feel bad, considering I am single and am not dating Boy A, so should have every right to shop around, right?

Anyway, any advice?

Extra things –

Boy A is a few months older than me, Boy B is about a year younger. I’m 17.
