Cuck Wanna Be asks for Advice

i am a submissive oral bi curious male......servicing men for many years and am more gay. i have had a few adventures with a married couple that i know.
She is kind of kinky and loved to watch gay porn and also really got off on watching me service his cock and rim his ass......he would always have a good cum and she liked to watch me take it down, and sometimes show her his cum before i swallowed. i am horny to lick out a creampie and i have had no luck in finding a couple into this. i am in a suburb of Minneapolis. i am concerned health wise and don't really know how to broach that issue. Any suggestions?

here is an old engraving that looks like a cuck situation.
