Hi, I'm 16 years old and I've been with my boyfriend for 4 months. When I first started having sex with him everything was normal then recently it's been starting to hurt during and after sex. It hurts more when he is on top. I've been to the doctors and a sexual health clinic about 4 times now. They took STI tests on us both which all came back negative. Then one person said it was thrush twice. I had cream and tablets for this and they didn't seem to work. Then the last time I went she said I was allergic to soap, shampoo etc (as I have sensitive skin) and also condoms (Latex). now after the treatment she gave me its back. I was on the pill when I was 13 then came off it but I am now back on it. (Lostrien 30 ). I've noticed Im not really in the mood for sex much but seem to do it quite often, when we do, the outside of my vagina seems to swell up and gets incredibly itchy - both inside and out - which tends to gets to the point where I just want it to stop and when I go to the toilet after to wee I get a bad stinging sensation. The pain is outside of the vagina and a tiny bit inside. This has never happened to me before and I have no idea what it is and why its happening now.
HELP!
Thanks
