There are no shortage of people who would say, like to have a threesome, be tossed over a knee and spanked, thrill to the idea of getting a blowjob from a stranger in a club, or would love to be thrown up against a wall and fucked, that never manage to get their fantasy filled.
Heck a lot of people would like to spend a weekend in Bali, and watch the sun set from the beach, and never manage it.
Part of being human is not having the chance or ability to get everything one may want/enjoy. But also, it's perfectly possible to be happy with what one does have in life, and be happy with ones life.
What would be sad is a person who can only focus on what they do not have, and live in misery, rather then see and appreciate all the good things they do.
