Follow up consideration; should fantasies be questioned at all, and if so:

Is this the flip side of being a closet traditionalist who wants to be cared for and to serve as someone’s wife, or rather, perhaps you should detail the other (emotional) parts of the life you’re talking about… What would be ideal about ‘the rest’ of the relationship.

…how does it differ from a loving and equal relationship that’s about sharing, consent, sensitivity, and mutual pleasure?

Is your fantasy of wanting to be dominated, one you actually want to be real, or is it best as a horny fantasy that should stay as such?

Do you think a fantasy character would have personality flaws that would damage your relationship outside of the sex? Would someone capable of doing such have personal issues that might manifest in other ways… And how much of this is really about your fears of society as an imposing force you cannot control in a way that you find self-actualising.

Do you think a different version of you would have different fantasies, and how different would your choices and views on life would you (and society) have to be to have different fantasies?

Are your fantasies, sociologically and psychologically situated in a way that you can affect? Or do you believe them to be a permanent aspect intrinsic to who you must be?

What sort of life security and society would you need to be the dominating figure, vs the submissive figure?

Just don’t use any lube and keep it as dry as you can. Size won’t matter. But then there’ll be no sex the next day, so it’s it even worth it?
