Having a shower just now and felt a spot on my outer labia. A hard pea of a thing. Knowing the water would make getting good purchase difficult, I finished my shower and dried off.
Then, with my thumb and forefinger and the gentlest of squeezes ... Pop ... Splat ... Into the palm of my hand projects a poppyseed of hard puss.
The rest was water and blood. I'll keep an eye for more.
My last one like that was in 2008 (is it bad that I remember?)
