Also, if you have one sexual intercourse encounter per year, you're not lonely? AND you could be pounding every week and still be lonely because the chemistry is not there, the love is vapid. People can just wank or pound for sexual release, but it doesn't solve loneliness. Hell, people are lonely in a household of 6 people. Why? Because everybody is doing their own thing, ambivalent of each other. Thus, they can be lonely.
