I have not tried the scrotum infusion but I have preformed the breast infusion on my self with no problems. A little sore the next morning. The saline is absorbed into the system in a few hours so there is no long term effects. I would like to find a lady that would try it with me. Meaning both of us would under go the infusion. It would have to be three hours of play time and of course I always treat the lady to dinner after.

I use butter fly needles so there is no repeated sticking the needle in to your skin. Every thing is sealed and sterile.
