Sex issues 😞

Devin • Due May 28th with Aubrynn Mae 🎀
So, last time me and my SO had sex, it felt raw in there even though I was wet which caused us having to quit so I'd stop hurting and him not finishing. I've never used lube before besides for just anal and my SO usually just gets me wet enough to where I don't need lube. Well, I thought I'd surprise him with a trip to the sex shop for some lube and lingerie. When he asked what I was doing I gave in and told him at the sex shop getting something for our next night (3 hours south of me due to work) and he asked what it was so I said I wanted to get a surprise but I got some lube that's flavored and one non-flavored that are both water based. He didn't reply so I asked what he thought and he said he didn't care that he isn't excited over anything sex related since he can't use it Until God knows when. And when I said I was gonna get lingerie he said please don't.. I'm 31 weeks pregnant and I feel like a huge blob and just want to feel sexy and wanted and he just .. Isn't doing that but anytime he wants phone sex or nudes or anything I give it to him. I just want excitement even if it's fake 😞 he won't even talk to me now cause I told him I didn't feel sexy and after 3 weeks of hearing "you're very sexy baby" it's just getting hard to believe. What do I do?
