There is no harm in celibacy. You can choose to remain so for as long as you like. But one thing has to be understood that it doesn't conserve or build any energy. At times suppressing sexual energy may lead to problems. Sexuality is a normal part of life as hunger for food or thirst for water. Even when one abstains from sexual activity, the normal semen production continues and it can get discharged involuntarily in from of nocturnal emissions (night fall). This is normal and shouldn't be worried about. Any spiritual process aims at a balance of mind, body and spirit. We cannot suppress one for the other. All have to be in harmony and needs at all levels have to be fulfilled. Wish you the best.
