I also take care of business myself most times and I enjoy it very much. Sex with the wife doesn't happen very often and it suits me and my CD lifestyle. But for me, the wife doesn't complain. She doesn't have much of a sex drive and she usually gives me a heads up when she is feeling frisky. She will usually make an appointment with me in the morning to have sex at the end of the day so that I can reserve my energy for it.
