Hey, I was wondering if you have written or could recommend any well written gay erotic cheating stories.

uh…as in, gay guy’s cheating on each other, or straight guys going gay, or what? I’m not really into it myself, but there are a few I’ve seen. One I especially liked was “The Rings” by cigarmtl on the old Gay Male TF Archive.

Don’t know if that’s what you’re looking for, but it’s the first thing that came to mind.
