Do I have an inverted sense of beauty?

I do the same thing with my husband and he doesn't mind it either.

I find it very relaxing and on occasion I am super happy when I get a particularly large specimen. I get a sense of great accomplishment after I have eradicated my husbands back and face of blackheads and festering pores.

I bet it's a primal instinct of some sort, sort of like how some primates pick at each other's lice.
