Re: What would being intimate often do for you?
In my marriage it would have given me the extra snap to my step to enable me to meet her requirements. My ex was pretty demanding (ironic given that she expected me to be easy-to-please). The way I work is that I really am happy to go the extra mile for someone, at least occasionally. But consistently stepping up and going "beyond the call of duty" takes energy; if a lady expects this of me, then she needs to be ready to give back.
In my case, she didn't, so I stopped caring so much, and it was downhill from there. Her matching my effort by providing sexually would have prevented that cycle.
