I'll answer your questions in the opposite order:

I tend to lean toward the Gordon Inkeles attitude toward sensuality in that all massage is sensual -- that is, it deals with the senses, particularly touch and to a lesser degree, smell if you put aromatherapy into it. I think there's a definite point where a massage stops being sensual and starts being sexual, but I think that is determined almost completely by the massagee. In other words, sensual does NOT mean sexual, but they can be connected.

Case in point: I have a friend who gets a massage from me about 2-3 times a year. We're both nudists and usually we're both nude when I give her a massage. Since she's the wife of my best friend I have never even considered taking the massage to a "post-sensual" level as it were, but there are physical changes that I can see in her that tell me that her brain thinks we're going for broke, even if neither she nor I really are.

Specifically, even though I don't massage the genital area, after several minutes of working on her legs, this woman's labia swells up and goes almost grape-purple. (It's similar to what I'm sure a lot of guys go through when they get an erection just from having somebody pay attention to the surrounding area down there.) Her breathing starts to quicken up and I usually calm her down without bringing attention to it by moving to long strokes from shoulder to foot.

I would imagine that when my friend and her hubby get home after her massage, he gets laid but good.

Now -- how does sensuality pertain to group massage? Using the same parameters above, it provides experiences that you can't have with one-on-one. We have a group of friends who used to have fairly regular massage nights. We had a table and floor areas. Someone would jump on the table, and other on the floor, and the remaining partiers would split up and go to work on the subjects. Some people simply got a good massage and a sensual experience they'd never had before -- groups of hands on them all at once. Others got more out of it, especially if they hadn't had any human contact for awhile. I can think to three different situations (all women) where they had orgasms just from having their legs massaged. Certainly not expected, but appreciated nevertheless!

What's to know about me? Nudist since age 13. Learned massage in college in order to meet girls. It worked. (I learned using "The Massage Book" by George Downing and Anne Kent Rush. Still the best book on the subject I've ever seen.) Wish I could find more people in the Phoenix area to trade massages with!
