harlequin181 Hello there!
I think chastity can really work in a marriage, but equally I don't think it is good for either partner to feel pressured into it.
To avoid any possible resentment further down the line, the belt has to be a free choice and should be treated as a highly appreciated and valued gift... something extra special, which it is!!
I know masturbation can short-circuit the sex drive and keep some people away from relations with their partner. This was the case for me so I understand the "😔" but, equally, I can definitely reassure you that my own belt has helped to bring my wife and I closer together.
It's worth remembering that it's possible to increase your belt use rather than go fully permanent, ...though being belted 24/7 has the advantage that you don't have to constantly readjust to and re-accept the belt itself.
How do you feel about wearing the belt at the moment? Can you imagine it being a positive, exciting part of your marriage? Do you enjoy the feeling of having to wait and does this make sex better for you? ~ All questions for you to think about. Best wishes!
