Ok, im not a woman, but, I have had sex with a girl with a large clitoris. As with anything, the more rubbing and grinding, vibrating gyrating (lol) you do, there is chance to cut, or inflame the skin. Also, as I said before, a enlarged clitoris may just mean youre sexually aroused. But if that is not normal for you, well then, if it does not go away, go see a Dr. You do not even have to see a gyno. A simple lotion, or, healing cream would help, but some may burn your vagina. That is why it would be best to get a script from the doc. I , myself, had injured my Penis through my pants, while playing baseball. A simple cream from a random Dr , and actually, it healed my penis to better than previous shape. heh,
Like i said though, some creams may burn ur vajo.
Like i said, You dont have to see a gyno,
Infact, you don't even have to see a Dr.
If you go to your neighborhood pharmacy and ask (the pharmacist) they will be more than able to help you! (Some Pharmacist , and prudes will shy away of course.)
I would hold off on masturbating for a while, keep the area clean and dry and if it does not improve within a few days, see your GYN.
