Should I be jealous?

This is kind of a two-parter.
Okay so hands-down, my current relationship is the best one I've ever been in. We never fight (except for the occasional bickering at the grocery store) and we're both very open and honest with each other. So I've told him before that I (ashamedly) am a little bothered by the fact that he's slept with more people than I have. 
The second part is (and I haven't told him this), he only came in a girl once but he refuses to do it with me. I feel like such a dork, but is it wrong that I feel jealous about either of those things?
