Okay I have a problem. I haven't had sex but I have participated in other sexual activities. And my vagina is very sore. I don't know what it is. It started hurting about 2 days ago. But there is no lump or anything noticeable to describe. It just hurts when I participate in sexual activities (fingering) What do I do?

We can't help you with your question if you don't explain exactly what you are referring to.

Um OK. Well basically since about a couple of nights ago, I have had some pain inside my vagina. Like it doesn't sting but it is sore. Like almost a throbbing pain. But as I said before there is nothing there that I can describe. It is just a throbbing pain when I am involved in something sexual.

Have someone examine you as best as possible, looking for anything unusual, even a pimple, believe it or not. They aren't uncommon around the entire pubic region. Or a cyst or ingrown hair in a cyst. All sorts of bumps.
Also, stop all sexual play to see if it goes away.
Then, a week after it has totally gone, see if it comes back.
If it does go to a clinic.
You can buy clear plastic speculums very cheap (try ebay) if you want to try examining that way. With a flashlight and a mirror, it's possible to look at your vagina yourself.

Thank you Joypuly. Do you think it is something bad? This has never happened to me before.
