I think many who’ve been into spanking their whole lives struggle to put into words why it means so much to them.
Spanking is just a expression of your sexuality. You don’t need to justify it, any more than anyone needs to justify what gender(s) they’re attracted to.
Because it’s non-penetrative, many dismiss spanking as “just foreplay”. As if proper sexuality must involve a cock going somewhere. This is not just an archaic attitude, it’s hopelessly wrong.
One of the main reasons I write is to elaborate in words what others have often imagined but struggle to express.
You may find it resonates with you, and helps you find the words to describe what you feel so deeply.
