Unless Bad is a woman getting
circumcized...
Assuming you are male, and I think another
post of yours might have indicated that,
here's a "Go Ask Alice" answer about
circumcision as an adult:

She says "temporary pain" but doens't
specify.
It's probably like any other minor
surgery- maybe big pain day one and two,
and it gradually gets better as time
passes.
Why are you getting circumcized at 16
might I ask?
