There seems to be a spectrum of orientations, rather than a simple gay/straight boundary. I would say that guys who are exclusively gay are "gay", those who are exclusively hetero are "straight", and all the rest in between are "bi"
The spectrum notion was just created to allow for bisexuals' behavior.
That has nothing to do with this article. This article is nothing but a propaganda piece seeking to head off another STD disaster. Remember AIDS was originally GRIDS.
Homosexual advocates had adopted the "one act" rule. One homosexual act meant the person was a homosexual. This was particularly useful tool used to count the prison population.
Nope they're homosexual, and most are not happy people, at all.
