I have had bumps in the inside of the vagina hole for the longest time. they do not hurt, burn or get bigger, sometimes maybe swell a bit but nothing that feels discomfort. When i do have sex and I am not lube correctly sex can hurt and i feel the rubbing on the them. When i touch them and pinch at them to see if they are pus like they just stay stuck to my skin and do not move and dont pop .... What can this be?
