I enjoy your intellect and sense of adventure, just as much as I do your body.
Your theory is a good one, both in terms of freeing your desire and the male perspective. Isn't a lot of sex, for either partner, about a bit of fear and about the way it mingles with the intensity of arousal? The vulnerability of nakedness, of acceptance and desire to provoke arousal in another. There's an additional vulnerability in penetration, whether that be letting someone inside of you or pushing inside of another. A trust and a gift, a responsibility to perform and to be attuned so to provide pleasure and satiate desire whilst always understanding what they need and where their limits lie.
For a man, as a cuckold, there is both a gift and a thrilling insecurity. There's his gift to the bull and the gift of freedom to his wife. Isn't it thrilling to see the way her body responds to his touches, her longing, her needs, her orgasm. And isn't there an exciting promise in all this, that once she's been fucked so well, she'll return to him, satiated, grateful. That's he'll get to experience her body all over again whether that be inhabiting her pussy once more, or cleaning and worshipping that pussy with his tongue, or just cuddling with her, wrapping himself around her as she tells him about her adventure and he, rather than feeling jealousy or dismay, will be focused on her pleasure and howz through that, he can feel the full intensity of his own lust.
