Little white bumps on my vagina like a zit, they don't pop unless I try real hard... but when I do a white head comes out? What's wrong??

I don't know why you would try to pop anything in that area, very dangerous thing to do, and quite frankly, how do you do it?

Saying you have little white bumps on your 'vagina' is pretty general. It would be very hard to see or do anything if the were on your 'vagina'. Your vagina is inside of you.

Just whereabouts are these bumps you are talking about ?

When it comes to the genitals my theory is
Take it to the doctor.

I wouldn't want to speculate and wait for answers
That could be misleading and cause you to delay treatment that needs to be started asap.

Because a diagnosis is not going to happen on line,
Go to where you get first hand and well informed information.

Since this is the Adult forum... how old are you or does this thread need moved?
