I haven't had sex for about 3 years now. I just don't bother. I'm not one of those pretentious virgin nerds who stalk these forums claiming they're asexual; I was in a very sexually active relationship before these 3 years and I definitely still get excited when I see an attractive woman. This is the second lengthy sexual break I've had (before said relationship there was also a 2 year break).
I honestly just can't be bothered with the whole romance thing. I've got plenty of other things to do, I'm not frustrated, I'm not unhappy and I am by no means lonely. Tried casual sex a few times but it just isn't really my cup of tea. It simply does not add anything meaningful to my life at this time.
And that's fine, really. Sure, I'll admit, the first month or so I was horny as hell, masturbating like there was no tomorrow. But that urge just fades over time. It doesn't go away, it just goes into 'sleep mode'. And it really isn't as dramatic as people would like you to believe. You just don't have sex, what's the deal? I think being unable to function without constant sex is a lot less healthy than not having it for extended periods of time.
