Beginning when I was 24, I started going to the Single Adult Labor Day Conferences at Glorieta, going to about a dozen in 15 years. At one of them, alongside the seminars and activities was a "Hug-In." In this, a husband and wife team led some songs and talked about the 'need' for physical touching [including that story about the baby some researchers tried to raise completely without human contact-- he died]. Then we had this list and illustrated drawings of about 15 different types of hugs, and we were to go around the room trying them, and getting the other person to sign our paper for that one-- just like "mixers" of finding someone left-handed, someone with blood-shot eyes, someone who owns a black labrador, et al. A "brother hug" was just both guys putting their arms over the other's shoulder. I don't remember any other of the names except the "octopus hug" (think legs) - that was the one that made everybody a little shy. But seeing that (as they had before, most likely) the couple showed a 'variation' of it that was less... intrusive, I suppose.
Anyway, I did that stuff in those days, and even ordered one of their red T-shirts, with a bear, which said "I'M A HUGGER!" But I assure you I wouldn't do that now-- nothing even close. That period of about 2-3 years was the only time in my life for trying to change myself into a "touchy feely" person. I had just come out of a really bad experience in a church, deploring the rigidity and the hesitance to reach out and relate and always falling back on 'Baptist tradition.' So I tried going that feel-good direction for a time before I gradually realized I'm just pretending with it-- I'm not really like that. So now, with the passage of another 20 years, I'm probably more like those "rigid, hesitant" old Baptists that I once had such a conflict with. In our current Single Adult group, I'm probably one of the least 'huggy' of all, and I'm sure most of them wouldn't believe I once took part in something like the "hug-in."
I think the ideal has to be somewhere between being stuffy and being huggy. Human touch is important, and there is a place for it among Christian brother and sisters. Don't deny it-- but don't make some kind of program out of it
