Does anyone else fight about sex?

My husband and I fight all the time about sex. He wants it'd everyday but I don't anymore. We used to have it all the time and we still have it atlease 3 to 4 times a week but since I had my laparoscopy done 2 years ago do to endometriosis I have alot of pain especially during sex. So I don't really have a sex drive anymore and my husband thanks I should give him a bj or something to get him off when I don't feel good and not in the mood for sex. I don't know what to do and I don't think I should have to do something when I'm not feeling well. Is this just me?
