Pain during sex?

Erica • 19 | Florida
Sex with my boyfriend has been really painful lately, but only with a condom (I'm on birth control). I don't have any STDs bc I've been tested and it's never been like this until I had a yeast infection like 3 months ago. Could it be that the yeast infection never went away? It's gotten to the point where I don't want to have sex :(((((
