"If the doctor asks to stick his finger up your rear to check your prostate you don't say er no thanks that's too private"

If you don't want your doctor to stick his finger up your butt, then that's exactly what you do. They don't have a right to finger your prostate, even though it might be beneficial to you.

If you don't want a medical procedure, even if it would be beneficial to you, you can refuse it. It is your right (at least in the US).
