I don't know about that. My own personal explanation for the reason the incidence of homosexuality is high among priests is because it exempted gay men from the strong social pressures of conforming by getting married to a person they knew in advance they could never really love during a time period (basically everything up to now) when being a priest was perhaps their only perceived professional option - that or being a florist, take your pick.  It wasn't all that long ago when I actually heard an elderly person say about a young boy, "That one's gonna be a priest." In other words, "He looks gay, so steer him toward the priesthood pronto so he won't be a social embarrassment to the family." So this is still happening even now.
