Yes once a partner has indicated they don't want to know about bondage or D/s play for once & for all, you have to live with it or look for an outlet. They ain't gonna change in a big hurry. This I know!
Anyway after all these years I couldn't imagine saying those things to my wife let alone doing it. 'Can you.....for me please dear?' Yeah right.
One small point re the feelings of wanting to Dom the lovely lady Warbaby- totally normal. I see a sexy lady in black boots holding a whip with 'that look' in her eyes sometimes & I think 'hmm being a sub for her mightn't be bad. (Now girls- don't get any ideas!)
Some people can do both, many of us have feelings either way.
