pelvic exams are NOT fun, but neither should they give you the feeling of being violated and raped. i think, mayhap, a change of docs would be a VERY good idea... I go to the health center at my school, and while it's no fun, i've never felt like the women with their fingers in my pussy were doing it for any other reason than that was their job and they were concerned for my ongoing health. With a LOT of cancer going back on both sides of my family, i have to echo galaxygirl with the sentiment that although the exams are a pain, i am fond of my body and would not like to lose part of it.
edit: or, at least, lose a non-vital part. i'd rather go 1-boobed then w/o a stomach, like they're about to do to my grandpa.
