Tired of always suspecting that your partner is cheating on you? Well, perhaps we can learn a little something from the multi-legged creatures on how male spiders ensure the faithfulness of their partners...sort of.

According to a new study conducted by German scientists regarding spiders' copulation techniques (it's times like this when you think scientists have waaay too much time in their hands), "males leave part of their sex organ inside their female partner as a sort of "chastity belt" to deter rivals." Hmmm..interesting, ain't it?

The Bonn University researchers found that by breaking off an itsy bitsy piece of their male organs inside a virgin female, sperm competition is reduced and further increases their paternity success. As you know, male spiders have to be real quick and fast in showing some luvvin' because it's only a matter of seconds before the larger female spider kills her partner. According to the study, this is how in over 80% of cases, the tip of the male's genitalia breaks off inside the female -- in the process of making a hasty getaway.

Now if only humans operate the same way -- we'd have a lot less one night stands and no need for various forms of contraceptive. Hahaha. Oh, which reminds us, for all the men out there, would you rather break off a piece of your woohoos or opt for the contraceptive dart gun? Your choice, fellas.
