What the hell??

OK, so my husband an I are pregnant right now. We tried for five years, we would have sex for hours at a time and it was beautiful. Now that I'm pregnant, saying we have sex for even 30 seconds is pushing it. He cums, and says "ahh that was beautiful", or "you're awesome" and not 5 seconds later he is passed out snoring while I'm laying there pissed... Its been this way for about a month now. I can't deal 😂😂😂 It makes me feel like, he thinks that I'm pregnant now that he doesn't have to prove himself anymore. Anyways, is there a NICE way of saying your sex game is weak and you're gonna have to try harder?? He's acting like a 13 year old boy that saw boobs for the first time that hold his load...
