Here are half a dozen recent studies on men & women.  Elliot & Niesta found that red, relative to other colours, lead men to view women as "more attractive and sexually desirable".  Holt-Lundstad & colleagues randomized couples to a "support enhancement intervention" involving shared gentle massage for 30 minutes three times weekly or a control group.  There were encouraging effects of the "warm touch" on multiple stress-sensitive systems including husbands' blood pressure.  Koo et al found that writing about how something good might not have happened (e.g. how one might never have met one's romantic partner) produced more satisfaction (with the relationship) than writing about how the positive event actually had happened (e.g.

When I woke this morning I lay for a few minutes, asked myself how I felt, went inside, and there's sadness, a sense of tears in my chest.  And when I touch the sadness, try to sense what it's about, it seems about "missing", missing warmth, the hugs, a sea of kindness and smiling faces (and, of course, there's my mother's illness too).  I guess that's what it was like for me at the group.  In the morning, every single one of the other 36 men seemed more than happy to greet me with a big caring smile and a big hug too.  A sea of kindness, smiles, warmth.  And I return from the Men's Group to a very loving family, a very loving wife, a phone call with a dear son, time with a loving mother - but I still feel this sadness in my chest.  Something partly about brotherhood, and I know I can touch this kind of feeling too after the four day Spring Mixed Group.  Something about warmth and love and acceptance and kindness.  A sea of it.
