im not sure about just a PA, but for my gf the piercings are a blessing and a boon. Every girl i've been with since getting them has loved them, since you get a little bit of extra goodness whenever i slide in, so its great for teasing by going all the way in and out really slow. Also, it supposedly feels great when you get just the right angle against her g-spot.
on the down side, it makes anal with my current really difficult, cause getting past the piercings really hurts her for the first little bit unless shes drunk. also the piercings can make her really sore after awhile, so we tend to try and keep actual penetration to around the 15-20 minute mark.personally im ok with that cause it keeps me from getting overly tired and i get my water break when i need it, but it interferes with any plans for a long slow session. also, if we have sex a lot over a couple days, her vag will get really raw in general and we'll have to take a day off.
overall its not a big deal, and we still have sex almost as often as we want anyway, and i definitely would do it again as well as recommend it to anyway who is brave enough to allow a stranger to approach you dick with a needle.
