Hairless Skin and Romantic Love: The Naked Love Theory

A striking feature of human beings is our lack of a thick coat of body hair. Since all other primates have such fur this suggests the primate ancestors of human beings likewise had fur and that, for some evolutionary reason, lost their body hair. But what could this reason be? There are various theories but none is fully adequate.

In a new attempt to explain this loss of body hair I argue that human hairlessness had its origin in the ancestral mother-infant relationship. In the “naked love theory”, as I call it, this hairlessness is ultimately the result of bipedalism or the ability to walk on two feet.

My Partner Has Been Less Affectionate Lately - What Gives?

My boyfriend and are have been dating for about 2 years and we are in our early 20's. Most of our relationship is absolutely amazing - we are great friends, our communication is wonderful, and our sex life is incredible. But lately, my boyfriend has been avoiding kissing me and being affectionate/loving in general. We still have great sex, but he seems distant and whenever I ask him about it he makes up an excuse like "oh, my breath is bad right now" or something. Am I approaching it correctly by being open? Any suggestions would be greatly appreciated!

Thanks for your question! I can think of a few potential explanations for the situation you describe. One part of your question that stands out to me is the length of your relationship.

Slowly Stroke Me (or You): The Power of a Soft Touch

To determine how the brain processes physical touch, researchers used a soft bristled brush to caress participants’ arms at either a quick or a slow pace. MRI scans of participants’ brains revealed activity in the insula, a region of the brain associated with emotional responses, during the slow, sensual strokes. Brain activity was similar when participants watched someone else receive slow strokes, but not when touch was directed toward inanimate objects.  

Morrison, I., Björnsdotter, M., & Olausson, H. (2011). Vicarious responses to social touch in posterior insular cortex are tuned to pleasant caressing speeds. The Journal of Neuroscience, 31(26), 9554-9562.
