For all you skeptics, (afraid males will spray), I have had 10 males in the last 20 years and the closest I ever came to this problem was that one boy would not squat when he peed. He was in the litter box, but he stood up. I countered that problem with covered boxes so his pee wold hit the back wall and run into the box.
I have definitely found that males are more loving and accepting of other cats. And more loving towards the human population, as well. My females have always been aloof or shy or persnikety. Out of 5 females in the past 20 years, I only had 1 that was a lap cat.
Just my experience, though.
