A psychiatrist that did a lot of research and polling, found that females were more likely to”fluid” in sexual preference than males. I can’t remember who it was, but my psychiatrist told me about the study. Another one apparently did research on sex, and after this supposedly “straight” researcher slept with both males and females, he stated that while his sexual preference was females, he enjoyed the sex he had with males more because he could give and receive. Don’t worry. There’s no such this as fully straight, or fully gay. Just go with the flow, go with what feels right, and spice things up a bit. As long as communication is involved and the other spouse is comfortable with things, go nuts. It may bring a lot to the marriage. Once barriers get erected that cause too many limitations in a sex life, it ends up feeling like a chore rather than enjoyment. So communicate things and see where it leads. It may end up blowing your mind and be an awesome experience. Plus, it may make him horny as hell too.
