I guess that I am just too traditional to agree for my husband to act out this type of experimentation. I am totally against allowing anyone into my bedroom (so to speak) except the two of us. I consider marriage between two people to be sacred. Introducing anyone else will only cause problems.
If I discovered that my husband was gay or had an interest in men, I couldn't get past it. If the urge were so strong that he revealed this desire to me, it would tell me that it was a very strong urge. I'd have to get out of the marriage.
My husband knew how I was before he married me. I didn't hide my way of thinking. If he wanted someone wilder or with a more open way of thinking, he should have married someone else because I made it very clear that I wasn't going to change my viewpoint.
You always hear people who want to rationalize their behavior with, "This is 2000's. You're living like it's the '50's..." I don't care what it is. I don't care if I am the only person in the world that is still thinking like the '50's. It worked for me my entire life. I've never had a shortage of men interested in me. Even if I did, I would not compromise my beliefs.
The end.
