...Good thing they're heros. Can you imagine the STDs they'd have from all that sex otherwise.

The funny thing about STDs is you largely only needed to be concerned about them over the last 300 years. As the world opened up because of exploration and people started to interact with other cultures the number of stds one would need to be concerned about were very small. Alot of STDs actually came from interacting with wild animals in a nonsexual way.
