Your ruling planet Mars is associated with the masculine energy, as well as your sex drive.
Chances are, if you're an Aries, yours is on the high side. You need that physical sense of connection both to burn off stress and to feel closer to your partner.
With Mars as your ruler, it may actually fall to you to find someone who can keep up with you in the sex department. Not everyone has the stamina you embody, so choose wisely.
If you're not compatible in bed, you're not compatible, as far as you're concerned!
