Same here and i felt always pissed off by the need to discuss things which are of course by their nature. As an example, a gf. usually expects to go shopping together, to plan meals and leisure activities, she will b***h if you prefer to spend the weekend with your computer, wants you to familiarize with her best friend, family, to appear as a couple, and talk, talk, talk.
My solution is to have affairs with married women since i'm so pissed by the above crap. Their hb's can do all that social stuff, i'm having fun with them once or twice a week.
Best experience ever, though, was an online online affair with a woman who was obviously capable for a compartmentalized lifestyle and sex life as well. However, that's not easy to find. Most women expect the social stuff.
