How do you find the p spot? I'm trying to help my fiencee with this and we are both having trouble. It is mostly for medical since he's been having a lot of trouble with his prostate and we've read that milking it will help. Any info is appreciated. We've read article after article but (lol) have had 0 luck finding it and we even bought a toy for just that. He's said it hurts more than anything and he's super uncomfortable
