I am 17 years old and have been dating the same boy for 2 years now, we started having sex about a year and a half ago and everything was fine. I'm also on the pill and we sometime use condoms. Well we would do it frequently and sometime for long periods of time until one day about 4 or so months ago where after we did it i instantly got a bladder infection. I went to the doctors and got it treated though and everything was fine. Well me and my boyfriend waited about a month or so after to start having sex again and when we did i could not handle it for as long as i could before it would get sore very quickly. Also i would have to wait a couple days to do it again, which i never had to before. It has now been 4 or so months and i'm still having this problem. In a way it feels like something changed with my vagina that day. I don't know what the problem is but i would really like things to be back to normal so i would love some help or anything that could help with this . Thank you
