I've been with my boyfriend (he's 29) for nearly four years and we have a 5 month old baby. At the beginning he had trouble maintaining an erection which he said was due to nervousness- he got over that in about a month and sex was regular and he seemed to desire me a lot as is typical. Then after a few months it dipped to maybe once a week, then once a fortnight. It was me initiating 80% of the time. He initiated maybe once a month. He moved into his parents at 2 1/2 years while we were saving and then I moved in too once my lease was up. Initially he was up for quiet sex or waiting for his parents to go out but after maybe two months he lost all interest. If I initiated he'd say no or ask for oral instead. He never initiated after this point. Had sex maybe once every two months. Then we bought a house and found out I was 31 weeks pregnant in the same week just before our 3 year anniversary. He seemed basically sexually repulsed by me pregnant. Had our son in December and for a while I was recovering and baby is a huge clinger so there was no chance of sex. In March baby became happy to chill alone for a bit and we had sex (I initiated) and once since (I initiated). He just seems totally uninterested in sex and it makes me really upset. For one being undesired is horrid, I haven't changed lookswise at all aside from a few stretch marks and maybe 5lbs after baby and I've had plenty of interest from other men over the past four years so it's not really a me problem. I get a few pecks on the lips a day and he'll jokily squeeze my boob or something like that. That's it. He is my favourite person and I love him terribly so the idea of leaving him over this is not one I take lightly. I've been on his phone and not found any evidence of a porn addiction or anything like that. I just don't know what to do as the situation and my future sex life is very bleak. Has anyone been through this??? Help!!
