Well… I think what they’re asking is do you want to be double penetrated or do you want to be one of the two penetrating the receiving member. MFM, FMF, FFM, FMM, MMM… Which is it for you?
My choice is MFM and FFM. I’m more of the quarterback type than receiver. ;)
I’ve done a couple of MFM sessions and the best kind are with a fully open minded chick who allows one cock up her ass and another in her pussy. And I’ve done a few FFM sessions too where pretty much the same applies for both women so they can trade the strap-on back and forth to both give and receive with one another and both experience the DP. Either way I’m penetrating the woman’s three holes and either depositing a load in her or glazing her face.
But hey, if you’re cool with a cock up your ass and another down your throat then by all means go for it.
