Dry Af. 😩

Hey ladies😁. This is my first post and it may just be bickering but I figured it might make me feel a little better to express my feelings to a group of women and not just my family. Plus talking about my sex life with my family is a little weird. Anyways, I've been going through some kind of occurring problem with my husband. He doesn't seem to want to have sex anymore and it makes me really sad 😔. We're way to young for him to use age as an excuse, he's 20 and I'm 21. We have one son and I'm currently 5 months pregnant with my 2nd son. He's in the Army and I'm a stay at home mom and I'm 100% sure he's not cheating I just don't understand why this is happening. It's now April and this started in October. We use to have a real healthy sex life and now we do it probably twice or if I'm lucky three times a month and when we do it it's not passionate, there's no forplay and it's really a total of 10 minutes and all it consists of is him getting off and that's it. It's hard on me because I'm already self conscious with the weight I have gained during this pregnancy and I've been thinking that maybe why he's not so interested in me anymore. But it really sucks cuz some nights he'll say maybe tonight we'll have sex and on those nights nothing happens. It makes me sad but it also makes me laugh cuz like who says that I don't wanna hear that. I'd rather him just start something in bed like normal people do. Not only that he will NOT go down on me, which is the worse cuz that's the best forplay to me. I don't see his problem with that cuz I don't stink and I keep myself shaved and clean. Anyways thank you ladies for reading and hopefully I get some feedback, if not it atleast felt good to express my feelings about this being that it's been bothering me for so long and I have no one to talk to.
