There is one particular implement that he likes and I hate. No matter how much he takes it easy with it (he swears he does), it just never flows into a kind of pain I can work with. It (apparently) works quite well for him; it never seems to fail to produce just the right combination of very red, very heated ass and very attitude adjusted me. But when he has been working for a while towards a very specific, very pleasureable attitude, adjusting said attitude just before the big payoff is not necessarily the way to go.
