3.) Do you remember any religious instruction addressing homosexuality?
Okay...time for me to talk to myself here.
By the time I was 9 (1963) I knew that I liked boys. I struggled with it for 5 years until my mother found out something was up. There was an awfully lot of guilt associated with this as I was Catholic.
When my mother found out I was gay it was 1968 (the year before Stonewall). She first took me to a priest in another parish for confession. He was an older Polish priest. He took my confession and gave me some small penance and when my mother went into confession he said 'go home and love your son.'
We were fine then, but then I needed to go see my parish priest and let him know what was up. I was an altar boy and was heavily involved in the church. This particular priest was an Irish-American - he always had a chip on his shoulder too (honestly, I think he was p.o.ed that he had chosen to be celibate). He had another brother who was a priest and he was always in competition with him (everybody liked his brother more). All of this to say that when it came to 'sins' related to sexuality he was a hard ass. He told me I'd have to start seeing a councilor at Catholic Social Services. The councilor had a M.S.W. (masters of social work) and I was pretty clearly the first person he had ever talked to who was openly gay. He didn't know what to do - but after reading up on what current beliefs were he told me that I needed to start dating girls and that if I couldn't change my sexuality that I'd have to live my life as a celibate to be a good Catholic.
This was all within the beliefs of the church. If you are not having sex in marriage you are committing sin. If you don't try to avoid it, you haven't made a good confession. Good luck being a horny teenager.
And that's what life was like in rural Michigan as a gay Catholic before Stonewall - for me at least.
p.s. - it wasn't my sexuality I changed.
