My boyfriend has been sore for just over a month now. Oral doesn't hurt him but everytime we try to have sex, he says it's painful. We've been together for a while now, and we've had healthy normal sex for about 8 months, this came out of nowhere really.. It's not a tear on the foreskin, and we aren't sure what's causing it.. I'm pretty sure he told me that it's hurting him on the inside of his penis as well.. Any ideas?
