In the image you can see a moving piston, however with a little effort you can imagine what this piston and the case around it represent! "Every object moving in a reciprocal fashion covers a distance, traveling in both ways." The sum of these distances is what is being calculated on Sexdistance.com. It works both for men and women!
Well, apart from being a fun thing to measure; some users that had issues with the duration of the intercourse, said that it is easier for them to think in terms of distance than having sex with the time in mind. It just gets some stress away when having sex.
By using Sexdistance.com you can calculate your lifetime sex distance, or the distance covered during any period of time. For example you can find out the distance covered by your penis, vagina, anus, mouth or tongue last time you had sex; just enter the necessary data: your maximum penetration depth, set "1" for times, then the speed (Note: Using the arrow keys on the keyboard can be more precise). Finally what makes it even more fun is the fact that you can enter the place you had sex and see how far from there you have gone on the map! Finally if you are proud of your result you can easily Share it on Facebook or Twitter!
