If it weren't important then no one would be talking about it. Even if you are asexual, NATURE says sex is important and it shows not only in humanity but in the animal kingdom as well

If it weren't important, it wouldn't exist. Hell if it weren't important, we wouldn't exist. And yes too much may be dangerous, but too much food is dangerous, too much wealth is dangerous, too much freedom may even be dangerous in this world. EVERYTHING has pros and cons. My answer to the question is yes. Even if you consciously object to it, it's nature. Plus if you "touch yourself" on a regular basis, then you need it just as much as anyone else. Sorry but it's true.
