i am in a momogamous relationship. ive been sexually active for about 4 years, have no stds and am really careful during intercourse. for the last few months, about 10 hours after intercourse, everytime, i get a burning sensation just inside and around my vagina. it feels similar to a yeast infection, but goes away after about 6 to 10 hours. whats wrong with me? it is starting to get to the point where i dont want to have sex anymore. no pain during intercourse, no lubrication problems. tried switching from latex to poly condoms, which helped a little. help?
