If natural means = anything animals do. It follows that murder is natural, and thus naturalness is a useless criterion when discussing human morality.
So, even under your definition, why would 'natural' be good?
You complain that homosexuality doesn't serve our instinct to procreate. To me, that is a positive about homosexuality! There are already too many people on Earth. We should be reducing the population through attrition as opposed to adding more to it.
So, in this sense, homosexuality may well serve our instinct for survival.
In any case, I find the whole argument to be silly. Most people don't choose who they love. They fall in love and decide what to do from there. And there is nothing inherently wrong with men loving men nor of women loving women. And, to go further, there is nothing wrong with people expressing their love for someone via sexuality.
Unfortunately, I am not bisexual, so I am not inclined to share sexuality with anyone who is not female. But that doesn't mean I am against others finding happiness in sex with whoever is willing.
