I have wanted a PA for many years but never had the nerve to go through with it, I have no other piercings or tattoos. I found this website and the experiences posted convinced me that I should just do it. So about 6 hours ago I did.
I went to Platinum Tattoo and Piercing (Perrin Beitel & 410) in San Antonio. The shop is real clean. Mingo listened to and answered all my questions. He took me and my friend into a room and I dropped trou. I did not watch the procedure. We had decided that I would be getting a 10g horseshoe or circle barbell. The initial puncture was not that bad but when he started to put the ring in and then when he put the ball on the end those caused slightly more discomfort.
I had very little beeding and was there 3 more hours while my friend got a tattoo. I am very satisfied with this experience and like so many others have said if you have been thinking about getting a PA then go for it.

-UPDATE- 10/11/09
OK so it has been 10 days now and no problems. Love my CBB. Sat to pee the first few days but have had no problems, I just aim it down even went out last night and no spray issues with the urinal. I did have a little blood spotting for the first couple of days but nothing sense. Went back the day after my PA and had both nips done and they were much more painful. I think if I would have had them done first I would not have done the PA.
