painful sex?!

I usually get super wet during sex but these last few days I haven't been as much. I tried to have sex with my boyfriend and it hurt so much because I wasn't as wet as I would normally be. We usually have good foreplay and amazing sex. But he thinks it's him and I'm not attracted to him anymore but I am and idk what to do about my situation. I've tried lube in the past but it always irritates my vagina. And we don't use condoms. What else can I do??
