Happened to me. Another med student and I (both male) introduced ourselves to to the patient and asked if it would be ok if we observed her fibroid removal surgery. She consented.

Then, after the patient was anesthetize but before surgery, the fellow (subspecialist trainee) doctor told us to palpate her fibroids, and showed us how. Basically, we had to stick our whole hand into her vagina and press it against our other hand on the outside.

I felt really uncomfortable about it, but I did it anyways because I was afraid that if I didn’t the fellow doctor would give us bad marks for not participating/not showing interest.
