This more accurately applies to those who go abroad away from husbands, wives, bfs and gfs. But the question essentially probes into the human need for intimacy.. or rather desire than needs..
Guys and gals, I am referring to the real act between two people here.. the sense of actual physical touch.
OFWs, those who work aboard ships, and just about everyone active enough.. I mean to exclude virtual encounters on e-media like skype, instant messaging, fb.. etc.. but real actual touch.
Sensitive topic I know, but I hope Istoryans have more sense than nonsense at this point.
