I hate to say it, and I hope these comments don’t offend but I’ll risk it:
Homosexuality has always existed among men as far as we know. I myself, having same sex attraction, know how ingrained it is, and I’ve expressed my struggles many times in confession. One priest I knew, God rest his soul and to anyone who would claim he wasn’t orthodox in beliefs I’ll argue til I run out of breath, told me his own opinion that there have probably been saints who struggled with the same issue.
That said, I think the priesthood once it became strictly for single men always attracted those with same sex attraction. It also attracted many heterosexual men of course, but I think it was a natural option for many who struggled. Why else would Dante have written of monks and priests in the circle of sodomites? It’s always been an issue. Even an article I read from a far left magazine quoted a priest who gave a talk at the height of the sex abuse scandals who said if you think the abuse began in the 50s you’re dead wrong.
In closing, homosexuality has always existed, I believe many priests and religious in the past experienced those attractions, and I don’t think the abuse issue just suddenly appeared in the 50s.
