i would go to the doctor just to get checked out. sounds like you have an incredible amount of anxiety over this.
the flip side of it is that probably whats happened is that he either "nicked" you with a fingernail or something like that, or you have a hemmorhoid (i don't know how to spell that word). i think that there is a 90% chance that you'll be fine in a few days, but if it has you about ready to flip out, then just go get checked out by a doctor.
also, don't be embarrassed about this. doctors see stuff like this all the time, and they see a lot worse stuff than some woman's anus who's had a finger stuck in it. that's a no-biggie...trust me.
hope you feel better real soon sweetie.
