How do you deal with a boyfriend who makes you feel conscious about your body?

My boyfriend took his pants off and got on top of me.. I was down to have sex cause it’s very rare he wants to. Anyway, he tries sticking his dick in me without any foreplay. I’m not wet. Completely turned off. Then he just looks down at my vagina and has this awful face like a face of disgust.. and then says it smells weird. Btw I haven’t showered today and yesterday we did end up having sex. So I know that usually that certain smell comes from having sex hours ago or a day ago. Anyway.. how would you deal with your boyfriend making you feel some type of way about your lady parts? I did tell him to get off of me and that sex is not happening.
