I am sort of confused...are you saying that you would like to have a male Dom and a female Domme at the same time? Or that you are a switch hitter who likes to be dominated by a guy but who likes to dominate a female sub?
Either way I don't see a problem provided all the players know what's going on and are ok with the arrangement.

I have trust and control issues so the only person who has ever really been able to dominate me is Sigel. I am a very dominant personality and I Domme Arch but Sigel does not Dom for him. Complicated I know but it works for us.

I know quite a few people who actually have a lifepartner with whom they are monogamous and a Dom/me with whom they do not have sex. I also know quite a few subs who have more than one Master/Mistress and Doms ho have more than one seb. The latter seems to be more prevalent but both situations can work beautifully or end catastrophically.

I know exactly what you mean! Sigel and I tend to trade power which feeds my need to submit when I need it. I find it next to impossible to submit to females, my natural desire is to dominate them. I have, on occassion taken it as a self challenge to find a woman who I was comfortable with and I learned a lot about the sub mind space and my own limits.
