Who says ?
If having genes which in some combinations or expressions result in an individual of a species having either a low libido or even 'swinging the other way' may have a positive impact on the survival of these genes.
Individuals within a population who are not burdened by the drives of sex or the end results (kids!) may be in a better position to assist the survival of the population in other ways.
When thinking about human evolution and survival you can't look at the way our populations live and interact today, you have to go back a few 100 thousands years and try and conjure up what the evolutionary pressures were.
Richard Darkins book, River out of Eden (or something like that) has an excellent stab at proposing a framework for evolution based around not just individual expressions of a genome (e.g. a human) but around of whole 'population' of 'well behaved' genes (a population).
Here's an interesting thought. A family line may possess a gene which results in a small number of offspring being disinclined to reproduce. An offspring-endowed brother or sister may rely on a childless sibling to baby sit for extended periods (this happens in quiet a few families I know). Perhaps helping to keep the family unit together or in the best case allowing the fecund sibling to have a 'weekend in Paris' with their partner and produce even more babies. What an excellent gene
