Oh Aurora, I'm so sorry! Please tell me you've told someone you trust about this? It's extremely important. If you haven't talked to your boyfriend about it, I would recommend that as well. Communication is extremely important, and this is something he needs to know if he is going to be in a lasting relationship with you.
That said, a gynecologist would be the person to talk to. They can help you get tested for STD's to make sure you don't have them, and help you prepare yourself for other things you may need to know before you have sex. If you do go to a gynecologist, be sure to tell them your situation, because they may think of something you do not. Going to a gynecologist before you become sexually active is a good idea anyway, so I'm sure you will find many benefits from it.
I'm so extremely sorry that you've had to go through this, Aurora, and I truly wish you the best in dealing with the situation. I'm a Christian too and I will pray for you, and I know this is just a forum so there's not much I can do for you, but if you think of something please tell me and I will be happy to do what I can for you.
