Having a sexual partner is better than doin' it on your own, or so says scientists. Sure, they're studying small creatures that can either reproduce sexually or asexually, but, sometimes, there's a little truth in everything nematodey. They also don't address the fact that, even if you've got a sexual partner, sometimes you do some "selfing" just because you're in the shower, or you're having trouble sleeping, or she's still alsleep and that morning weathergirl is showing a lot of clevage - come on, science, can't you explain that a little bit better, in a roundwormed-related metaphor?
