You have porn to deal with it.
People who get trapped for days in an elevator drink their own urine.
This is also a way to deal with scarcity of a resource for a basic need.
But at least urine does contain water, while watching porn is not an interaction with another person at all. If this works for you good for you.
Also I disagree with most the prioritization of that particular model, sex does not belong in the first layer for one and most of the other layers don't necessarily always have to follow the order. Basically I think the prioritization is subjective, e.g you might want social status over even the first layer and as the model is mostly about prioritization I might as well disagree with the entire model.
There are some people with low sexual drive or asexual and this is true for them.
But let's face it life is born to reproduce itself, this is universal, not only for humans. Most healthy persons have a quite strong sexual drive. Most women less than men, but they do have a much stronger instinct to get kids than men.
Prison inmates, who would be otherwise straight engage in homosexuality to fulfill this need.
Even most of catholic clergy (who are supposed to practice chastity) have an active sexual life:
"A 1992 study of several hundred clergy found that 62 percent of male clergy and 49 percent of female clergy had been sexually active since taking their vows, and the men had had more partners--about a quarter of the clergymen had five or more partners while only three percent of the women had that many."

I understand that the decreasing level of testosterone in men can bring to question more and more if this need is basic.
This can be seen as natural selection or the symptoms of an alienated species which damp testosterone and boost CO2 levels, with an uncertain and possibly not so long future ahead.
Bad generalization, not saying it's wrong but it only explains things for a few people that fit the criteria.
At least I provided a link. You say this reason accounts only for few cases while there are other reasons which explain the majority of cases which you do not even mention.
Am I supposed to believe you because you are an authority in this field? (but also authority should not be trusted right? after all you mostly distrust Maslow)
