It affects our lives. We in the Western Hemisphere are steeped in Judeo-Christian tradition and that can only mean one thing: repression.
Sexual repression, that is. A look around mental health offices we will notice that most of the complaints therapists hear are all about relationships and how they have gone bad. And how sex has become stuff of dreams.
Some will say that this construct, the west's religious background, is no longer in operation. Ha! No longer? Then that means it was there once. As if that weren't enough to cause the downfall of governments...
While in gay relationships what seems to matter is the myth of youth and in heterosexual relationships the myth of thinness - women seem to think that their men want them thinner. It could not be farther from the truth. Men prefer their women plumpy and exuding with power. For ages on end men have been looking for comfort and they will lay their heads on willing, fleshy bosoms.
The above seems to indicate that humans operate by intricate mechanisms not yet explained by science.
It is hormonal. It is in our chemistry. No amount of bible-thumping and scarlet wearing will stamp out the age old urge to go out and liaise with other human beings - gay or straight.
If you get that, fine. Otherwise, accept your sexuality the way it is and make the best out it. No use beating yourself up about it (please no pun). Let us all live and let live so that we can preserve our sanity.
