>>3434449There is such a thing as oxytocin.
I understand if you've never felt it in your body before, but it's the hormone that makes you attached to things and people and pets.
It's released a little on any sort of touch with others and released greatly when being intimate.
To put it simply, if you never touch yourself to your waifu you will become detached from them. You might not want to involve imaginary men in your material, though.
