This is an extremely muddy issue because there is such a huge amount of ideologically-charged bias over the issue in today’s world. An LGBT enthusiast is likely to do whatever it takes to downplay any possibility of an alternative lifestyle to just following their preference, and they’ll spend plenty of time convincing themselves of that as well. Unfortunately, the opposition hasn’t been any less of a problem, especially among fundamentalist Christians, that want to treat homosexuality as something that is mysteriously chosen without any inclination. They’ll acknowledge inclinations towards every other evil imaginable (like heterosexual lust), but SSA is treated like an exception to the rule. This is something that has been detrimental to opposing gay marriage, because many opponents have been blanket labeled as in the dark and clueless. And to be honest, I’m not sure opposing homosexual behavior can make too much sense unless you also consider it in light of why contraception is evil, which is something protestantism abandoned in the earlier 20th century, so it pretty much comes down to the Catholic Church being able to address this issue with complete thoroughness.
I know at least one story of a guy (he was Mormon) who liked men, but married a woman and had children with her, and only admitted in his later 40s that he had SSA. According to him, he didn’t at all find vaginal sex to be repulsive; the experience was pleasurable for him, but he didn’t have the desire towards his wife that he had towards men. So could a strongly SSA person just validly marry someone and enjoy married life in spite of their inclinations?
When you think about it, there were men & women throughout the centuries in Christian Europe that must have had SSA, and presumably not all of them ended up in religious life. This is something each individual would have to discern and I wouldn’t exempt men from it. Even though men tend to be more visual than women, they still like sex, and just on a biological level, any stimulation will work. The joy of children will also greatly reinforce the bond, and as the years go on, a person gradually becomes less and less amped for sex anyway.
