I really like the ornamental type piercings... Mrs Spoo's nose and navel are pierced and I think it is sexy as hell. I don't have a lot of experience with the more sexual piercings (hood, nipples, etc.) so my jury is out until I get more familiar.
So far when I have played with them I feel kind of remedial - like I am working around it and not with it. When I have gotten into a groove and kind of forgotten that it was there, it has been pretty cool - and actually gives me a little "tool" to work with.
I have played with a woman with her hood pierced and it kind of made it easy to find things the first time out
