GUYS: I like a guy but am going to hook up with another one. Bad idea?

I'm an 18 year old girl in college. I have a guy I like (K) at college but a fwb (H) I met over winter break. Nothing was happening with K before winter break but since then we've been hanging out and I think he might like me but am not sure. But spring break is in 2 weeks and I want to have some fun with H since we're both attracted to each other and K and I are hanging out once a week but nothing more. Over break H and I will probably just be cuddling, making out and touching each other. I haven't had (oral or otherwise) and am not going to do that with H, but he is totally fine with whatever I want to do. Both guys are really sweet and I don't want to hurt K, but since we're not in a relationship and I'm not sure if K likes me, do you think it would be a bad idea to have fun with H over break? H knows I like K and is fine with that and knows that if I get into a relationship with K nothing is going to happen between us. But K doesn't know about H and if he does meet him I'm going to introduce H as my friend, which he is. Btw by "hook up" I DON'T mean having any kind of .
