Have not done anal with it. I've only done anal with my woman a few times and she doesn't like it too much. I probably would get something in there, but hopefully it'd piss right out afterwards.
Havn't had unprotected sex since I got it done in Feburary. I had an extremely long healing and didn't want to expose it to her bodily fluids until it was 100%, as you aren't supposed to expose any fresh piercings to someone else's bodily fluids. That combined with the fact that she's not on BC means that we have to use some form of protection. I don't mind too much though, condoms help to hold it to the side a bit making penetration easier. The ring has to move to one side or the other in order to insert. I usually reach down and hold it over even with the condom helping though.
