that does make a difference, you should have made that clear at the start!!
then talk with him, find out where he's at, is he ready for such a step with you, or anyone else, consider what it may do to your friendship and how he sees you.
I'm 54 with a 23 yo bf so its not an age thing, but do consider very carefully where this will lead you both and how it will impact on you both.
however, don't have sex with him just because you think he's 'hot' that sounds a bit like taking advantage of him?
