I'm 17 years old. Recently my boyfriend and I started trying to have sex, but since I still have my hymen and he's so big we haven't been able to actually make him fit. The day after that, my vagina was burning, itching like crazy, and there is an odorless white discharge. I thought it could be a yeast infection, but its not thick or chunky. I don't want to go to my doctor because I don't feel like its too serious, but I'm not sure what's wrong!
