Introducing BDSM

I am Dominant and have been into BDSM since my teens. My wife is not and are sex life has been slowly dwindling. She shows no interest in BDSM but knows of my love of it. Any ideas on whether I could introduce it more with a hope to improving or sex life??

What sort of things have you tried with her?

Some restraints, spamming wasn’t popular and sensory deprivation

How was she with restraints?

Yes she liked it but maybe more for me. Think she struggles to totally let go

Have you thought of a bdsm questionnaire?... When myself and my partner wanted to explore different aspects of sex we both answered the questions and then got to see what each other liked rather than have a full on conversation about it as my partner could be a little shy at telling me what he really likes. There are plenty online for you to have a look at...xx
