During my many years of being a client, all of my providers have been gay excepting one. The exception was a bi man with whom I had some phenomenal times. We gave each other what each wanted, and he never failed excepting when he changed his sexual orientation status from Bi to Straight.
After the pandemic brought us some semblance of normalcy, I engaged his services on four occasions. Two of those times he had me "climbing the ceiling"--for he certainly knew how to "apply the wood." He would always have me in such a state of euphoria that I had to ask him to stop or to slow down.
I don't have heart problems, but with the expertise that he rendered, I thought one perhaps would occur.
Shortly after those last two sessions, he changed his sexual orientation on Rent.men to "STRAIGHT." I managed to see him, but unfortunately for me, those sessions were NOT the ones to which I looked forward.
On one of those occasions I kindly addressed his status; he became offensive, and I ceased talking to him about this matter.
I do know that his sexual prowess was definitely NOT satisfying; it was quite, quite underwhelming as contrasted with the times during a five or six year period that we had been seeing each other.
So, in response to the initial question: it's primarily Gay with me unless the Bi guy is interactive and meets my other needs/requirements for satisfaction.
