It's very common for guys of that age to experiment, though perhaps not as common to continue so much full-on sexual stuff.

I was in the same situation with a couple of guys at the same age. I don't feel particularly guilty about it but do feel it steered my preference for boys.

Were you/we guilty? We were still kids, and didn't know much about this whole new world of nice feelings. I can't in all honesty see any thunderbolts coming on us from heaven for that stuff. And believe me, I'm the world expert on guilt now!
