Help!

So my boyfriend is very self conscious about his performance in our sex life due to cumming fast but he always makes sure he takes care of me first and I continually tell him that It doesn’t bother me cause I cum pretty fast too but it’s to the point we’re we only do it once a month even tho we are trying to make a baby! And I feel like a crazy person 1. because I like sex and 2. I want a baby and you have to have sex to make a baby and 3. It makes me start to feel self conscious. I need help! Has anyone else gone through this and what did you do to get through it?!?!
