I'm posting this on my girlfriend's behalf as I guess I'm more worried for her than she is herself.
Anyway, about two and a half weeks ago, she got a yeast infection which she treated with a gel. We had sex a couple of times while she had the infection (before she realised it was anything) which was fine, but just over a week ago, we had sex again (thinking the infection would be over - there were no symptoms/itchiness). After sex, her vagina was quite red and she had a really bad burning sensation inside of her to the point where she cried. I obviously felt awful and we decided not to have sex again for at least a week. Yesterday, we started having sex again and this time, sex was painful but otherwise okay afterwards. Then today, sex was great, but post-sex, we noticed some red eczema-looking dots around her vagina as well as dry skin and yet again, 5-10 mins after sex, she had the intense burning sensation again. We suspect that the redness could be due to poor shaving, but she's usually good at that, so I thought I'd add it in the post as well.
We were both each other's first, so I doubt we could be talking STIs. We also don't use condoms (she's on the pill).
Any suggestions as to what could cause the discomfort/burn/eczema would be appreciated as well as treatments.
Thanks for your time!
