Not having sex for prolonged periods of time is sort of like starving yourself for no reason - it's a physical pleasure and a part of life. My Fi struggles with this still because I like committed relationships and 'ideas' that extend toward the future so I am still tweaking it but it makes logical sense to me most of the time. The fact is 1) I like sex. I find boys real attractive and yummy. And 2) The chance of meeting your soul mate is really slim so I don't feel that it's reasonable for me to wait that long.
