When 95% of people hear “Homosexuality” they immediately, and correctly, think of buggery between two males.
Any nuances are a moot point. Two “friendly” males who are practically intimate, is a moot point. Sex is implied in “Homosexuality”. And at the core level, it’s an imitation of Heterosexuality, the default of nature. Copulation, between men and women, is the core of sexuality. Any corruption of copulation, is perversion, extending to taboo and fetishism. There are centuries of Guilt laden within hedonistic acts. Christianity has long been a tradition shaming and teaching populations of this guilt, “Sin”. To divert the natural sex drive other than to its purpose, procreation and reproduction.
You can call it “recreational sex”, empty sex, meaningless sex, inconsequential, masturbation. Homosexuality, then, is recreational. A fad.
Another hint:
Many humans are drawn to and attracted by taboos and fetishes, what society tells them is “evil and bad”, they will want more and more. It’s about denial, being denied something, being denied access, that gets people off. Thus, for example, with homosexuality and homosexuals, being castigated and bullied, along with the shamefulness of homosexuality, draws some males into the fold. It becomes enticing for some males, then, to engage erotica, to what they are disallowed, to pursue “what they know is wrong”.
Many people are driven by such fetishism which results and develops into psychological fixations. Like other addictive personalities and manifestations, like a drug abuser addicted to heroine or cocaine. Addicted to lifestyles and taboos. Same with the pedophiles and other deviants. Addicted to what society disallows. Like a thief who steals, not for the object, but from the exhilaration of committing a crime, the adrenaline rush, like a sports-junkie, getting a high from “living life on the edge”.
There are many factors, reasons, and causes which lead to homosexuality, or other perversions. It’s a pity that these aren’t discussed within threads like these. People only scrape the surface, not really wanting to dig deep within the topic.
