Our anatomies are not compatible in the traditionally sexual sense. Humans find this sort of thing either erotic or embarrassing. To me it’s neither. I enjoy his mind. He enjoys mine. I think he’s delicious, which complicates things. He is attracted to me whether or not I like that notion. So, I suppose to answer the question in a succinct way, there is petting, titivating, kissing, and fluids. For him, it’s physically satisfying in the sexual way, for me in a purely gastronomical one, with the added enjoyment of having made him happy.
And yes, I do protect him from my teeth.
