Marital sex problems ☠️🙄 and im on 20

When me and my now husband first met, he was so sweet caring and generous. And man the sex 😍😍. But i got pregnant... Ever since then sex has SSUUUUCCCKKKEEEDDD! Did I say sucked? We are now 2 years into marriage and 2 kids in and it's horrible. He was not working until our first was born and now he works. But anyways, he doesn't turn me on anymore, not a single tingle. What in the hell do I do? Bad sex, horrible communication and Im so clingy 🙄. Literally feel disgusted when he tries anything sexual to me. I DONT KNOW WHAT TO DO. I wouldn't be so stuck with this, but I love the hell out of him
