Guilts me into sex

So I dated this guy for almost two years and throughout the entire relationship he would sort of guilt me into having sex? Like, I wouldn't want to, I'd be tired or not in the mood and when I would say no he would always get upset and say things like "we only ever do it when you want to" or "I have to wait for you to be in the mood" or "we never have sex when I want it" "I'm always having to wait for you" but I mean.....isn't that the point? Two people both mutually decide to have sex and then....they have sex. Or whatever the case may be. After a while of him doing this and me getting tired of all of the arguments I would just go along with it to avoid an argument and just have sex with him to please him even when I didn't want to.  Is it normal for that to happen in a relationship, one person wanting to have sex, the other one doesn't but does it anyway to avoid confrontation? Cause I mean, sex or the similar are a little different than just deciding what to watch on Netflix or where to go out to eat that night. Oh, well we picked what I wanted last time so you pick this time and I'll just suck it up cause that's what you do. We broke up a couple months ago and though it wasn't the main reason why we broke up it did come up in some discussions and he would always get mad and say that he never wanted me to do that or that of course he never forced me into anything and that he would have been fine if we didn't have sex but I mean, he never was. Am I over reacting about this? Or did I do the right thing? Should I have stood my ground or what else could I have done? It just seemed unhealthy to me I guess, thank god I left him. Any opinions?
