17 Sexy Science Facts To Liven Up Parties
7. Gymnophoria Is The Word For The Sensation Of Being Mentally Undressed

Gymnophoria is the sense that someone is mentally undressing you.
Apodyopsis is the word for the act of mentally undressing someone with your eyes.
Incidentally, there is conflicting research as to where men and women look first when taking in the opposite sex (mentally undressing them or not). According to one study, 47% of men look at a woman's breasts before they look at anything else on her body (although that is the Daily Mail reporting, so who actually knows) but, on the other hand another study has found that men are more likely to look at the face (rather than the genitals) than women are.
6. Straight Guys Love Penises

Speaking of staring at genitalia, when two neuroscientists conducted a systematic review of our online porn habits, they found that men search for penises almost as often as they search for vaginas.
Whilst it's not exactly a revelation that men are obsessed with willies, just ask Freud, it was found that the size and type of the penis featured in porn was just as important as the lady parts. The neuroscientists think that this could have a basis in our evolution, as penises have multiple social purposes - from denoting dominance to marking territory - and it makes sense for blokes to be hardwired to grab a cheeky look every now and again.
