I was married almost as long as you when my marriage crumbled. It was me who lost interest in sex and marriage. I wasn`t in the mood for escorts , but I was in the mood for spicy flings with married women as long as they were young and hot.
Within 3 months I started a long term relationship with a much younger very sexy and beautiful (single) Quebecoise lady. We were both looking for love and along with the emotional gratification came great sex. I didn`t see my first escort till that relationship ended 10 years after we met.
I think that`s what you are looking for. BTW I never saw a marriage counselor.
You know the expression shit or get off the can......well have a real serious talk with your wife and if she refuses to meet you half way then mention divorce and see how she reacts. Unfortunately covid has put a crimp into socializing but travelling and putting your golden tongue to work is your best bet to meet a new love.
