About two years ago, I went off my birth control to save money and because my boyfriend and I were living in two different countries, so I didn't really think I needed it. I was on one called Estrostep. Anyway about a month after I went off my birth control my boyfriend came to visit for a week. During that week, sex was painful to me (it had never ever been before) but I kind of endured it for the week knowing I wouldn't see him again for another 5-6 months. A couple of days after he left I got a call from my gynecologist saying that I had some evidence of a yeast infection. I never had one of those before in my life ever before either. So I took some medication to clear it up. Fast foward to 6 months when I moved over to Australia to be with my boyfriend and attempted sex once again and it was painful. I was extremely tight and dry down below and if attempted sex continuously then I would end up with bloody sex and a rawness feeling. Moreover, over that next year I suffered from weight gain and painful constipation. Some doctors i've seen have mentioned it can be vaginismus. Now there is about a 30% chance of my body lubricating itself before sex and can only have sex for about 5 minutes before it starts hurting. I've grown extremely depressed and my confidence in myself has dropped tremendously. What is happening and how can I fix it?
