Were I blessed to be in such a threesome, I would want contact with the other guy. But I identify as bi and would probably make sure that's clear in negotiating the encounter.
Ever had the opportunity. Have done FMF twice and both times the girls ended up more interested in each other than me. Would I do something with a man in a threesome…maybe.
Been to a couple with my gay cousin. Intriguing. Actually had sex with a woman in my car in the parking lot. Also had my cock rubbed while standing at the bar. Felt pretty good.
I had my own company thus avoided sexual encounters albeit I can’t say it never happened. I had sex with a significant number of our customers over the years. Still do with a few even after I sold the company.
