Thanks for all the alerts to possible risks. I was not aware of risks from PS, now I recall the girl shaved therefore her tiny hair was rubbing my skin and could open up some part of my skin, passed on a decease to me. I think taking a test frequently is not a good solution, the ultimate solution to avoid unwanted decease is to stop the hobby and not go to any semi-legit or above spas. Once you get in a semi-legit or above spas, things could be out of your control for many reason. I think it is not worth my while to go for some fun and end up with some serious consequences, so I am quitting. Good luck guys
