I thought I did, with my 2nd bf. He was a schoolmate in high school. I went to an art school and was involved in performing arts and was involved in a lot of school programs. We hung out a couple of times and ended up making out and having sex. Then we dated, after a few weeks he broke up with me and told me he had a gf in a different country. After a few months we reconnected and he came out to me as gay. Then we because friends with benefits, and would play together. Now he's married to a guy. But then I realized, I didn't convert him, I just helped him come out of his closet.
