Fiancé not wanting sex as much

momof2

We have been together for almost 5 years. We live together and now I’m 17 weeks pregnant. Its just like he isn’t into it anymore and when he does he’s not that into it and it’s just does it now randomly because I really want to. He loves blow jobs and I do this often, when ever he ask and just surprise him with him because I want him to know I want him and I want to be there but it just doesn’t feel the same in return. It’s like all he wants is either blow jobs or porn when I’m not home, don’t get me wrong porn is fine and I like it but I just want to have fun sex again, not like it’s a chore for him... it kind of sucks...
