The odd phenomenon of cycle of emotions
It can work out that Satipatthana can help one let go of desire. Usually, as you may know, Satipatthana isn't to suppress but to see the truth.

Our sex drives are strong though and if they are too strong for standard Satipatthana then they can be surpressed by other techniques like the naming of the parts of the body, that can have a repulsive affect on sensual desire. An other good technique to turn one off quick is to look at autopsy photos. That is also good for reflecting on death. These little practices really are very supportive of the main Satipatthana practice.
