Sex in space is not just a good idea, it's survival.

Earth is in space, too, so really sex in space isn't anything new.

People have been making love and having sex in space over the thousands of years that our ancestors lived and traveled in small hunting-and-gathering bands. Earth is in Space.

Sex is an emotion in motion.

Sex × Technology = the Future.
