Well, I would have to agree with both Bruce and beale. If you feel truly bad about it then perhaps it is not the best thing for you to be doing. On the other hand, how open minded is your hubby?

Some spouses can recognise the need to pursue other avenues even if they themselves have no desire to participate. We have befriended more than one female submissive who's husband knew about our relationships and I even made friends with one of them.

You never know. Perhaps your husband would be interested in the lifestyle. I don't know him so I can't say how he would react. you'd have to use your own judgement on that one.

Also, perhaps part of the reason you feel guilty about playing with this male submissive is because he is male. For some reason it is worse to "cheat" with the partner being of the opposite sex. I know that TG would much rather see me with a female Dominant than a male or another female submissive (probably part of that whole male fantasy thing)

Anyway, I am sure that you will make the right choice. My best advice is that if it makes you feel guilty and if it feels wrong, then it probably is.
