I think it's a combination of some lubricant, just spit will do. When you are alone, use whatever you want as a lube whilst stroking your cock and balls full-length. So I mean down to the base. Proceed to your buttcrack, then slide into your butt. Make sure it's all lubed. Insert as many fingers as Read more… possible and grab around the base into the section your prostate's at. At the end, the best prostate orgasm is to edge yourself by igniting both dick and balls and prostate using both hands.
As for two, the prostate orgasm is even better. Once your partner has loosened you up they could weigh on top of you lying on your back with your legs wrapped back and lick and finger you up. If your back gets tired just switch positions. Strapon is good too, focus on the angle. Otherwise the most pleasurable position is to squat on the partners face and smother them, make them tongue you whilst rubbing into their faces as the lie on their back with the head hanging loose so as to grasp it and steer it. It is the most intense.
