Beswitchingly:
Yoga is an intriguing tip, thanks. I'd like to get into that myself (I'm Mysc's Dom, if you hadn't noticed that already) but I'm afraid I lack the attention span. Still I'd like to try, though.

As she said, it's not a problem of compatibility or different needs. We're still finding stuff out (well I am) but we're doing fine. It's more that once she gets going really well, it's like a gyrator being fed from some invisible powersource - she keeps and keeps going, past the point where my stamina runs out. I'd love to be able to do more, but it also has to wind down sometime.
It's hard when you're new to get started, yes. Then it might get really, really hard to find a good way to stop...
