It seems more and more "straight" married men have a curiosity of experiencing some form of MM Play.
The way I see it, is they have a hard time getting to grips with it due to upbringing and social stigmas that still exists. The most prevalent would be the irrational "fear" of "being gay".
Whilst FF Bi curiosity has become socially acceptable in many respects, the same is not the case with MM curiosity.
Many of these men would be quite happy if their spouse voiced her desire to explore her curiosity, but fear even raising their curiosity for fear of judgement, shock or the possibility that she might ask if he is gay.
As someone who has dabbled twice, my experiences have me seeing myself as predominantly straight with a preference for predominantly straight who is cut and of good proportions. Interaction for me excludes kissing or penetration.
I am curious to hear couples and ladies views of their men, or men in general having a Bi curious side.
