Burning pain

Hey ladies. Okay so during sex with my boyfriend sometimes my vagina starts to burn which makes it a bit painful.. I don't know if it's because it is too "rough" where he's kinda banging into me or what cause I know I am not dry. Then when he finishes I become so swollen and the burning is so bad that when I go to pee it hurts and I can barely put any pressure to wipe. Does anyone ever get that problem??? I get a lot of yeast infections and BV problems but didn't think they were connected?
