sexuality
Ran across some of my old porn folders, dating back to when I was in college. There's an awful lot of stuff that I don't think I really had as much interest in at the time as I thought I did, but I thought I was sort of supposed to. My porn folders became progressively less heterosexual as the years passed, which directly tracks the reduction in my homophobia. I was extremely socially conservative when I entered college.
Things change. I still haven't shaken off the past enough, though
