My wife expresses almost no interest in sex. Whave been married for 28 years. Sex has always been an issue. It used to be every few weeks or so. At present it has been over four months. I only seem to get "pity" sex - if we have an event we have to go to which she wants to enjoy (like a wedding, a cruise or an out of town convention -I try to take her with me). It seems she just has sex when she needs me in a good mood for a few days. The longer we go without sex the more irritated I get. If I bring it up she just ignores me or initiates a disagreement (in my opinion) which pretty much rules out sex. She says I don't make her orgasm. I have spent hundreds of dollars on vibrators, toys, creams, lubricants and the like. There is little or no kissing or intimacy when we have sex. Any kissing is generally on my part. I am an average guy just extremely frustrated.
