C/s. I'd say "pretty well". The thing is I know my body, so if something doesn't feel right or could feel better I usually communicate about it. That probably takes the pressure off the learning curve quite a bit.
On a side note, I think that's what differentiates great lovers from good lovers sometimes. Some people are just really good at paying attention to subtle cues. Some people really really LISTEN to your body. Others are just blessed with favorable anatomy so pretty much anything they do is going to feel good without extra effort. I think it's that extra that makes it exceptional though.
you and I need to get a room already.
