Yes, this can happen due to the friction. Please tell your boyfriend to be gentle. Young guys have no clue about what would actually feel good. Give it a couple more days and it should go back to normal. If not, then yes. You should see a doctor. Planned parenthood is an option for young girls who do not want to involve their parents. They'll see you. But you need someone to get you there. Otherwise, you could just say you have a woman issue and want the doc to check you out. But sincerely guess it will be back to normal in a day or two. And then you need to set the boyfriend safe that this is no way to treat your lady parts! good luck
