Being a bit of a scientist, myself, I would like to see a few more studies before drawing any meaningful physiological conclusions:
- Men's reaction in various American cultures to sleeveless shirts and/or short skirts.
- Men's reaction to pictures of women they have a romantic relationship with, fully clothed and less clothed.
- Women's reaction to similar and analogous images.
It does indicate that the argument that men should simply deal with women dressing how they want to dress might have a few holes in it.
No pun intended.
