It might be some kind of infection like a UTI or a yeast infection it could also just be irratated because of some kind of hormonal change or even a slight allergic reaction to something like laundry soap if she is worried about it take her to the doctor they would be able to help out alot more all peoples bodys are diffrent so it could be just about anything
Sounds like a possible yeast infection. You can buy awesome over the counter meds to take care of it in 1 dose, up to 3 doses. Topical vagisil creme will help with the outer symptoms, but will not treat the infection itself. I know latex does that to me, so If you have changed your contraceptives (eg spermicide, condoms, etc) it may be the problem. Also if she is taking any meds, especially antibiotics such as penicillin, that can cause infections as well. Best of luck to her, being a woman ***** at time! =0)
it could be a simple yeast infection, sometimes it's not severe enough to form any discharge however it does burn, itch and cause dry uncomfortable intercourse, I would suggest re-phresh?? I think it's called, also be sure to always be careful when you first start having sex, (insertion) because it can cause tears and irritation if there is not enough lubrication.
