Hot is not always good, hot means you could get burned.
Ah a challenge, I had a situation very similar to yours once, a long, long time ago. The guy I was attracted to told me point blank that he wasn't into "relationships" ah, I thought, I can change his mind. Yup the puppy love eyes, the challenge that he presented, what did I get out of it? Well, we ended up in bed a few times and he never did make a commitment to me, apparently I was a challenge too. ;)
