Let me start by saying that I'm currently living and studying in Japan, so it's not easy for me to go and see a doctor currently, especially one that specifically specializes in Gynecology.
I am a 22 year old female and I lost my virginity about 4 weeks ago to my current boyfriend. The first week of sex was relatively fine pain-wise, although the first time hurt like hell.
About 2 weeks ago we met in a hotel as he was in my city for business. At the hotel he fingered me and then he left to attend a business dinner. The fingering was fine and there was no pain, but when I went to the bathroom afterwards there was a strange tan colored discharge.
After he came back, we started having sex. For some reason it hurt quite a bit, but I didn't say anything in fear of ruining the mood. He pulled out to switch positions and thats when I noticed some of the discharge from earlier on his condom.
We stopped immediately as he was worried and I wiped myself and noticed a brighter blood (not discharge) was now coming out of my vagina.
The pain is localized to the left side of my vagina. It is not extremely deep, but it is not surface either. There is always pain during sex, but only during sex with a slight localized burning sensation for a short while afterwards. There is not always blood, only sometimes, and it is always small amounts.
I'm really worried about this as I'd like to enjoy having sex with my boyfriend, but sometimes the pain is so bad that we just give up.
What could this be? Should I be worried?
