Hi , i am 17 sometimes my vagina burns after i have sex when my boyfriend cums inside . its not all the time though & the inside of my vagina is red?

Could be : Vaginal burning after intercourse can be caused by several things.Itcan be due to a sensitivity to a condom or vaginal lubricant (especially the "warming " ones) or vaginal dryness at the time of intercourse producing what is in effect a friction burn but it can also be due to a vaginal infection.An exam would rule this out. There's a slight chance of a sensitivity to something in the sperm.

GYN: I would suggest several things: first- a thorough GYN exam to rule out infection or inflammation. Secondly, spend at least 15-20 minutes on prolonged foreplay so that your vagina is well lubricated or use a water based vaginal lubricant. Third, make sure to empty your bladder after intercourse and lastly: frequently change you sexual positions: It is time for a GYN exam- abstain sexually until see
