People do engage in homosexual acts in prison and heterosexuals even develop long term romances with other men. You can call it something else but that does not change reality- it is certainly a sexual experience.
When I say “become homosexual” I mean to say they start feeling desires they have not previously felt or considered. Nothing can stand before the fire of Torah and if a human being with powerful, deep-rooted homosexual drives falls once along the way there is no excuse to actually perform the act itself or demand it be respected. Making a public national statement embracing homosexuality will do much harm (just like legalizing prostitution and gambling will even if people will do it anyway).
