Im in a similar boat. Been married for 35 years. Its been sexless for the past 25-30 for various reasons. Still love my wife and would do almost anything for her. I would say we have a happy marriage. I get my sexual urges fulfilled by regularly seeing sp's and going to mp's. I dont think my wife is entitled to know what i do in the sex department or even care for that matter. I dont tell her because as with most civi women i dont think she would like to hear that i have sex with other women outside of our marriage but on the other hand i dont think shes that naive to think that i dont. All men have urges that need to be fulfilled its just nature.
