I can answer that in a reverse way,l as a Bi Man since 1964,have been marries twice (divorced & widoewed),and both my wives knew l was Bi,my present Gf who l live with knows and understand that l like man sex she even sits and watches some times.

She knew I was bi before we were married, actually got fucked in the ass the first time after we were married during a threesome with a friend. Thought I’d found the perfect woman! Turns out she hates it, gets ultra jealous. Over the years I’ve come to believe most women hate it. Statistically speaking there’s women out there but they’re more like unicorns.

say they would never date a bi man. They see bi men as being one step away from "gaysville" (their word not mine).
But as a gay man, I have to say they aren't far from wrong.
I know there is this spectrum of which people talk when it comes to sexuality, but every bi man I have met has said he is way more attracted to men than women.
This doesn't surprise my female friends, which is why they don't date them. They feel these guys would really rather be with men, but societally they aren't comfortable with making that commitment. So they date, and marry women.
And then many cheat on their woman with a man on the side. Which brings potential disease, etc. back to their bedroom.
This is just their concern and their take on the matter.
I suppose if both parties are aware and open about it though, it's their decision to make.

When I was dating my first wife, I had known that she once dated a gf of hers. She kept in touch with her and we had double dated with her often. One night the gf's dated canceled. The three of us hung out, drinking and playing dice and cards. We ended up nude together and had a threesome. Happened a couple of more times. The fiance then wanted to have another guy join us. How could I say no? He was a coworker of hers and I knew him too. He joined us and we had a good time also. We were laying in bed, he rolled over her and began to suck my cock. The fiance was very turned on. "S" sucked me dry. He was very good. I then went down on him, and I really enjoyed it. I swallowed his cum as well. I was hooked. S and I would even get together, just the 2 of us. He and I would get with a friend of his, and she was amazing too. She was the one who turned me on to curvier women.
Second wife and I enjoyed being with couples. We even found a regular couple that we would party with and he was bi too. Oh, the experiences and memories! Now that I am older, haven't been with a guy for a while. The itch is still in me.
