Lack of sex

I haven't had sex in like two weeks and I'm miserable. I try to ask hubby what's wrong and why he doesn't want to fuck me, but he just tells me that he does, and that I'm the sexiest woman on the planet. I'm 15 weeks, I get that he may not want to hurt my feelings but I'd rather just know the underlying reason and not be wondering if he's getting his nut somewhere else. This bums me out, I need my babes touches and attention, and porn and masturbating are getting old
