My husband?

So I have a hard time with the fact that I was my husbands first and I wasn't his first it didn't bother me but is rare occasion it does in a wierd way sometimes I feel like and I know it sounds dumb but was she better than me! And the other day he was texting his cousin and she read the text out loud while we were at dinner because it was suppose to be a joke and I get It but he had told his cousin that his ex was bad sex and I was a perfessional I get it was suppose to be a joke but at the same time why did he bring her up at all why was he thinking about it!!
