Hello,
There is something wrong.
I had sex with this guy and 1 month after or so I started getting these little tiny bumps on my vagina. It is on the rear end of my vagina kinda going toward my anal, but more toward my vagina and almost on it, going inside.
It doesnt look like warts at all. It looks more like a rash. but some of the bumps are bigger then the others (like about 4). It almost looks like a pimple but kinda more like my skin grew.
Then at the bottom of my vagina, there is white stuff just sitting there. It is kinda inside. but I can see it. It wont wipe off when I try to clean it either. It is very clumpy. The white stuff went away almost the other day, but it is slightly there still.
I have NO burning or itchyness. I feel normal. The big bumps sometimes itch, but rarely. I think thats my mind just playing tricks though.
Once a month when I pee, the inside of me kinda feels weird. Not the outside, the inside feels weird, like it kinda hurts, but it doesnt burn when I pee.

Does anyone know what this is or what this sounds like????
Any type of help would be great.

I have a Doctors appointment next week. I am just scared to find out.

Thanks for any replies.
