tug of pain

When your pubes stick to your shaft while you're doing something, you become constantly hurt with the pain of your hairs feeling like they're plucked. It's not a good sensation (especially in public) since you need to adjust the hair so that it doesn't stick. This is usually a problem for men who don't shave or trim their pubes. I'm sure men out there know what I'm talking about.

Sherlock: I experienced the tug of pain on the way here.
Watson: Oh jeez, that's sounds... painful.
