Getting laid off is a major issue for men in terms of their sex lives. It doesn't matter what a man's relationship status is at the time of the layoff, there is likely to be some impact.
Most white collar men in relationships are dumped due to their layoff. Men in non-marital relationships who don't live with the girlfriends are the first ones to get dumped because it is easier for those women to exit. Those girlfriends usually exit within 3-4 months, which is often not enough time to get another white collar job. The married men and the men living with their girlfriends get a little bit more leeway with the breakup because those breakups are a little bit more difficult. These men might get 6-12 months before the divorce papers or breakup happens. In this market, that might not be enough time to get a new job.
