You aren’t being old fashioned at all.. I agree. A stolen kiss between a girl and a boy at a Homecoming Dance is cute to me. A full groping event is crass.
I agree, and with TV and all that jazz being so much about even cohabitation, people of either same or opposite gender associations showing little value, it makes me want to just get shows like “I Love Lucy” or other old fashioned sitcoms on video. Yes, it was way before my time, but the behavior of a married couple on I love Lucy is more modest than plenty of regular unmarried couples. Again, IMO, devaluing things that were once genuine, valued, tokens of affection, is part of the reason why people care less for aberrant sexual behaviors. The interesting correlation is that while people have been making their affection less value, even those practicing homosexuality have gone a similar route, even back during the 1950s, I don’t believe homosexuality, especially male homosexuality was too deviating from the general population in terms of health issues, both mental as well as physical.
The correlation of homosexuality with drug use, relationship violence, suicide, and sexually-transmitted disease has consistently been pretty strong, at least in modern Western societies. Going back to classical times, things are a little different - for one thing, we don't know much about their experience of disease, beyond obvious catastrophic epidemics.
I have a theory that, given their instrumental view of women (they keep house and have babies), men in ancient societies diverted the emotional drama that now characterizes less-successful heterosexual relationships into homosexual interactions.
