Actually, sex is a good example of Simple Harmonic Motion and conservation of energy.
When you're having sex at a regular rhythm, it could be likened to the representation of a sine wave where the
frequency would represent how far one thrusts, and the
amplitude would represent the strength with which the man penetrates the woman. And slowing down or speeding up could be translated as lengthening and shortening the wavelength (
phase shift).
Now when a man and a woman have sex, it sometimes happens that both partners experience simultaneous orgasm. And for some reason I don't understand, the woman usually feels invigorated after the orgasm while the man becomes drained.
In that sense, you could say that energy has been transferred from the man to the woman, but since they both climaxed together the total energy in the system remains the same.----This, ladies and gentlemen, is a perfect example of
conservation of energy.
On the other hand, if the man experiences premature ejaculation while the woman is left high and dry, there is net loss of total energy in the system, and this exemplifies
non-conservative work.
As you can see, there is a
lot of physics involved in sex.
