According to Osho, your suffering persists because the vow of celibacy is a violent repression; repression drives sexuality from its natural center into the mind, returning as thoughts, fantasies, and dreams. Life cannot be changed by force but by awareness: understand, watch, and let natural experience teach you—then desires relax on their own without vows or compensatory disciplines.
If you try to crush sex with a promise, it hides and pops up in your head; calmly understand and watch it, and it settles.
