What sex ?

m

So lately I just have not been motivated or think about having sex with my husband we just moved 2 wks ago and things have been a bit hectic with unpacking and mind you we have an 8yr old a 17 month old and 4 month old twins.. but i'm just so exhausted he says he has been hinting to me about being horny I guess I pay him no attention, even oral I love giving head but I'm just not into doing it anymore that's not normal for me , he hasn't gotten head in a month or so ..btw he also got a vasectomy back in July and missed his appt to check if all spermies are dead¡ and i'm also worried about that but a few months back he made a comment about my weight and I took it really hard so my thoughts are why bother being intimate with me if u have an issue with what I look like I wasn't pregnant back to back or anything (smh)I've told him I think that's my real reason for not wanting to have sex with him am I wrong .. do I worry he might cheat its it's a slight possibility but I'm not sure how or what to feel anymore ..
