Now TG that all depends on the type of relationship that you and your submissives want.

If they want to be in the type of situation that you have described then go for it, just so long as everyone is happy.

Though I will hazard to guess that there are subs out there who will accept that their dom is poly, but do not want to participate in a poly relationship themselves. This would require a bit more work, and as long as you can give all of your submissives the love that you want to give them, and as long as this is done equally then I do not see any problem.

Though to do this you will need to reafirm that you love them just as much as any other, and with proper scheduling things can work out. I have seen it, though not with live in couples, but it is damm near close.

I have gotten the same when talking with some of the poly couples that I know who are not into BDSM.
