I have mostly paid to see switches with the aim of spanking and being spanked (and caning as well, of course). Spankees and switches typically cost a lot more than the sums mentioned so far in this thread - £130 ph is cheapish in the South East although you can sometimes get a better deal for longer sessions. I've seen dommes charging less than this but equally many charge similarly. I'd like to know who charges less than £100 ph!

I also like time. I prefer a session that allows us to get to know each other a bit. I find the spanking part works better if this happens.
