Catholic guilt runs deep. I know a guy that came out this year at 31, which is fine, but I saw him kissing a guy when he was 18-19. He was engaged to a woman until 2022, too. He wasn't even under the influence, he just played it off as experimentation at uni which reaffirmed his straightness.
Indoctrination sucks. I was raised Catholic, but haven't set foot in a church for the express purpose of going to a mass in over 13 years.
I took my mom and grandma up to an ancestral grave yard, and we visited the church next door, because most of the people buried there were married in that church. I'm one of those people who can feel the "vibes of history" when I'm standing somewhere significant, and I found myself acting on my best behavior while inside, even though we were the only people there.
