Sex is natural, so before I even give my opinion, its impossible to forget about it. We are technically animals. Humans reproduce through sex so without thought, a human is born to breed more humans, its something that can' be forgotten as long as the human race plans on surviving. As long as you are healthy in terms of whether or not sex can actually kill you, it's going to be a part of your life. And as far as I know, sex doesn't threaten your life until you're in old age.

But if it were possible to forget sex, the right thing to do would be to forget about if you were in fact, sexually impotent. It'll only slow you down. There is nothing worse than wasting your time on something unachievable.

But giving up sex wouldn't be such a bad thing. Seeing as though sex is a major part of any human's life, if you were one of the few to actually give it up, you could focus on other things and excel in whatever those things may be. There are people who roam this world right now, young and old, who don't plan on having sex ever. Doesn't mean they won't satisfy themselves in other ways but by doing so, they really can focus on other things they're passionate about. It not a bad idea when you think about it.
