Could be laziness in my old age, but I've recently began utilizing a very simple technique to protect my sheets during ejaculation. I jerk-off every night before sleep. I've started leaving my T-shirt on, instead of sleeping completely nude. When I feel the inevitable spurt coming, I just raise the bottom of my shirt, and trap everything on my belly and chest.
On a cautionary note: my timing was off the other night, and I received a large shot to the eye.
