I went 15 years without a single fap or sexual encounter at all, from age 25 to 40. If you repress it enough, then by the time you're 40, you'll have to fight to KEEP an erection, rather than to eliminate it. I fap once per month now, just to make sure all the plumbing is clear, but it's an effort to make it work. So, it is possible to completely transcend the natural urge. Keep going!
