So that's it. I was wondering. Do you mind me asking where you found this definition? Perhaps you have a dictionary you can recommend?
I'm beginning to think English lacks useful neat terms. In my search for a definition I came across the "profile" of one Japanese guy on the 'net in which he professed, under Skills, to 三点責め. It just wouldn't have been the same if he'd had to have said, "Skills: sexual pleasuring a woman with both hands and my tongue"!
By the way: if I had provided the context in which the excerpt was taken you would probably translate it as, "I have great interest (in it) ...."
