+1 for jax nailed it.
As for me. Back when I was married, my wife asked me to go down on her after I filled her. I was curious, so I went for it. It wasn't bad. A few months later, she wanted me to kiss her after I came in her mouth. She held the load and pushed it in my mouth.
We never had a cuck relationship. Just the two of us. But it started my thinking
Now that I'm with my girlfriend, I have licked hers clean most of the times she has gotten it from someone else. It's one of my favorite parts about her getting strange. I don't think that makes me gay. Bi-sexual at best. Because the thing is, I like pussy. Gay guys don't.
I would say that I'm bi-curious, because I have taken a cock both ways. But I was not attracted to the guy, and never have been attracted to a guy. I find women beautiful. And as far as sex organs, I like them both. Just not attracted to guys. I couldn't kiss a guy.
Labels are just labels. You shouldn't try to force your opinion of a person on them. I do what I like, as I'm sure you do. I don't care if I'm straight,bi,gay, or purple to you. It's what I think and want that matters
