Madison, are you sure you have a yeast infection? Are you having a lot of itching and a whitish discharge?
First, calm down, it'll be ok. Apply some neosporin to help the healing of the rubbed raw area. For the yeast infection, use PLAIN Dannon yogurt mixed with a little water to make a slurry. Put it in a douche bag and do the douche before going to bed. You will have to treat with the plain yogurt douches for 5-7 days to kill off the yeast and get things back to normal.
Or, you can buy an over the counter Monistat 7 day treatment. Use it at bedtime so it will stay inside you longer. Don't use the 1 day stuff because it's too strong and causes some women to get a bacterial vaginitis.
In the future, always wash your hands really well before any kind of sexual stimulation. Make sure your vagina is clean, too. Especially, make sure that your sex toys are cleaned with antibacterial soap. Don't use your own saliva as lubricant.... if you have oral herpes, you can transfer it to down there. Try some baby oil as a lubricant, but never touch your fingers to the bottle opening... let it dribble out onto your fingers or vulva. This way the oil never becomes infected with bacteria.
I hope this helps...... really, it'll be ok.
wow well try goin to the doctor? with a friend or sombody else
