You missed the point. How about: I'll go without food or water for an hour and you go without breathing for an hour. Human needs need not rise to the standard of oxygen to be significant. Especially when you're talking about lifespans.
Sex is not an (individual) human need. Ever. Regardless of the length of time you arbitrarily decide on. There are people who have died from suffocation, dehydration, and starvation. They are relatively common. Dying due to sexual abstinence, never heard of even a single case.
That is my point / argument. You may disagree, but I'm not gonna listen much unless provide some evidence.
