Good question. I have had to learn a variety of hugs and handshakes over the years as I've travelled around. My favorite man to man hug (very popular with the samoan and maori guys) clasp each others right hand by the thumb crossed over and held at the chest. Touch foreheads and clasp each others shoulder with your left. It's intimidating and cuddly all at the samr time.
I often find people running from me as I like the good ole bear hug when I have not seen someone in a long time. But thinking about it, most man to man hugs I've come across have some sort of handshaking too. With women I try to stick to the hand on either shoulder, groin apart hug. Unless I know them really well then its just sort of a come here you bear hug thing.
But I have a question here. Should a male shake hands with a female in a social setting to greet her upon being introduced....When ever I'm introduced to a female by friends I always feel so awkward shaking hands. It doesn't worry me in a buisness setting but at a social thing it feels wrong for some reason.
I am somewhat like fraggle, with my girls its like tackle them kind of hug, and my guy friends its one arm around their shoulder. but there are some guy friends that both arms around their neck. two guy friends will hold me for a long time like hey dont want to let go. One i think nothing of it because he is married and he and I are justg close, the other it makes me wonder. One time we ran to each other and hugged for a while...our friends keep telling me there is something there but he keeps denying it...hmm
