inappropriate jokes

My husband keeps making jokes about his past going to strip clubs or sleeping around with hot blondes, and it's just really starting to get under my skin. I'm 10 weeks pregnant with his child and don't feel my hottest, which I've told him and he just laughs like it's silly. He made so many in a row today that I started crying and he just giggled. I know he thinks it's great to see me get jealous and angry because then he knows "I want him" but come one, he should know I want him by the fact that I'm carrying his child and trying to have sex with him! Just needed to vent. Ugh, some guys.
