ouch that is a harsh tone for an honest comment. Prostate simulation or ANY anal stimulation needs lube especially if its the first time. Simple dry skin CAN feel like a nail when its going in your ass for the first time. Have you tried it? At the very least if your going to comment on some ones pain tolerance, you should experience it. Know where they are coming from when they say something hurts. Any way if you want to sexually stimulate some one so they will sexually stimulate you so you can get off? Try having sex tends to work.
