I have been having pain in the vagina and also burning.?

sounds like a yeast infection or urinary track infection. Go to the doctor!!!

Lay off the masturbation for a while. Get a boyfriend to get you more excited and do it with you. It's more fun that way.

To help you heal, take a soak bath with baking soda, epsom salts, etc. You could use a tea bag solution in the bath or on a washloth and wear it in your underwear. Diaper rash ointment should help too. Leave it alone, otherwise. Any chafing will iritate it. When using the toilet, pat yourself with a damp paper towel. Do not wipe- pat.

Next time you want to masturbate, if you feel you are not wet enough use a lubribant made for that like KY jelly.

If you've masturbated with dirty fingers or fingernails, you may have caused and infection, hence the burning and pain. If this continues, go to your gynecologist.
