Welcome to Zity !
Last year when my doc was examining my testicles, she asked me to "lift my penis up and away". When she asked, it wasn't erect, but about semi. Then as I held it, it started to grow.
Would be neat if the doctor had an accompanying nurse to do the honors, huh.
Any other time any other doctor examined my testicles, my penis was never touched, whether standing or lying down.
