HOMOSEXUAL, because there’s nothing GAY about it.
Respectfully, No:
HOMOEROTIC, because there is no such thing as functional sex (that is, sexual reproduction) between two members of the same genetic sex (that is, binary male or female).
The raison d’etre for the very scientific concept of sex is sexual reproduction - versus asexual reproduction - via penile/vaginal intercourse between a sexually mature male and a sexually mature female.
Anything else is merely some form of eroticism, whether legal or illegal.
When I was a Biology major, arrogant secular scientists asserted that “sex” was all and only about spreading genes in the pool, and that “love” was merely an illusory biochemical impetus to do the spreading.
Now the arrogant secular (Marxist) scientists assert that “sex” is the illusion, while “love” is the reality.
I do not believe that love is an illusion - but I do believe that homosexuality is a (deranged) illusion.
