Hi friend, I should let my wife answer this but I may can help. This may be due to intercourse. You do need to go to the doctor , but I might can tell you what it is. This could be from your boyfriend. It does not sound like a STD ; it sounds like he drilled you , too , hard. I know this sounds awkward , but it could be true. If your vagina is tight and probably not use to having something in it ? I would guess his penis would be about 7 inches ( average) . Please tell me what your doctor says. Dr. Clay Ellis
You must go to the doctor, but I can provide some possible causes.
1) Yeast infections can cause labial swelling and itchiness.
2) Did you have sex just prior to the swelling? Sex can cause swelling just from friction.
3) I suggest you don't use any scented products to clean your vagina. In fact, overcleaning it can cause irritation. I just use unscented soap and water. Don't spend too much time cleaning it!
i should add that i've had a very light fever. 99.7 at the highest
i've also had really low temperatures too 97.6 being the lowest
my temperature normally sits around 98.6
