How do so many guys go years without intimacy?

I?ve seen this a lot specifically on Dating.mobi there are guys that go 15+ years without romance or sex and I just wonder how? Like does it become less desirable over time?
Do you just pretend not to care? Do you get angry or scared? Is there a possible reason why? Just so many questions.
Edit: i think the ?how? part of the question is coming off the wrong way it?s more like a ?how do you handle it? not a ?how did this happen?. Apologies for the misunderstanding. I promise I?m not trying to insult anyone I just wanted to hear that perspective instead of just assuming this is how that specific group of people feel.
