Hi Chaim!
Here is a quote from the GYE Attitude handbook (page 6):
"Some people think that if they are unmarried and have no outlet, they cannot possibly remain clean indefinitely. This is patently false. We have helped many Bochurim to achieve complete abstinence and we have many testimonials of Bochurim who were addicted and broke free using the right tools, the right attitude and determination. In some ways, it is even easier for Bochurim to refrain completely from lust, since they have no need to indulge in it at all. Below is an excerpt from an article on the Internet over here:
If a male doesn't ejaculate for a long period of time nothing noticeable happens. There is no buildup of pressure or extra sperm. Our bodies are always reabsorbing and disposing of extra material, including excess components of the ejaculate. It is perfectly natural to not ejaculate for a long period of time. There are no risks or heath problems associated with not ejaculating.

Hatzlucha, Ah Gitte Vuch and KOT!
