I was sexually active about a week ago and a few days later I had a horrible itch on my knee. It was an insect bite of some sort, I figured, even though it's winter and I've been indoors, which struck me as odd. Well, I've since developed a light smattering of the bites on my legs, my lower belly and back, and — disturbingly — in the crotch area, especially along the line where my legs meet my pelvis.

The bumps are small, itchy, easily scratched open. Do crabs go so far afield of the pubic region? The timing is too suspicious for me to blame bedbugs, and I don't live in the NY area where it's so bad, but the symptoms I would think match better with that nasty. I can't see anything, but I'm a girl and that's not the easiest area for close inspection ...

Any diagnostic help would be so, so appreciated.
