I do the same thing, actually. I had a spider bite that got really infected and puss-filled. The doctor had to cut it open to drain it, so I asked if I could watch. Lol. She was like "Uhh...If you want to...it's going to be pretty gross, and it might squirt out a little"...She made me want to see it even more, lol. It was really cool to me I'm such a weirdo sometimes.
yup i do the same thing.
it's really bad when i get a pimple...especially one of those really big, painfully pussy ones!! LOL...which i have one right now...and it's driving me nuts! i become obsessed with it...to the point where it looks a thousand times worse from playing with it so much, rather than leaving it be!♥
