In my opinion, sexuality is something deeply personal not limited to biology but integrating all areas of human life. What els can you expect me saying:)

:D

condoms alone are far too unsafe

I wouldn't say they are far too unsafe. Just not perfectly safe. I also find that the simple technique of pulling out at the right moment is just as effective as any pill!

Otherwise one could just as well say that food is an existential instinct and that we would see a feeding instinct live out uncontrollably in public or at the dining table. Which is not the case.

It isn't the case because there's plenty of food. But in times of war, people start eating their pets, and stray cats and dogs and rats. And in certain snowy situations, they even eat humans!

All I'm saying is that statistically, given how human males are, if xyz conditions occur, certain other things will start happening more, just like an increase in poverty unavoidably leads to an increase in crime. There's just more pressures, so the 'weakest' or most exposed parts of the window will crack. I'm not saying that all the parts of the window will crack.

If man or woman may suffer from having too little sex, my compassion is limited (actually to zero), because sex is not about life or death. Nowadays, certainly not at all.

I think some people can actually go crazy without sex! Monks in isolated monasteries see so many visions for a reason! :P
