Yes not all monkeys masturbate but many do, as do many other mammals. So u don't really have a point except for one cherry picked study. But i didn't expect more from u since ur claim is bogus either way.
Let's try that again. Humans are not promiscuous species. Humans are mono or polygamous. Just 11% of the mono/poly monkey species masturbated with ejaculation. More than 50% of them NEVER masturbated.
When you push monkeys aside, masturbation becomes magnitudes more uncommon.
You are going to compare humans to insects next?
Nice attempt to ignore the facts in the study. And yes, if "masturbation is natural", we would've seen it across all types of living beings. But guess what, it's rarer than winning the lottery if you count mammals and even rarer if you include other life forms.
So you just admitted to making dinner for yourself and sleeping long sometimes on a Sunday. That means that you enjoy cooking dinner for a man and spending time in bed with a man to get cute and snuggly. That means you are gay. That is your logic. You do these things with a man and you enjoy them.
Not that there is anything wrong with that.
Cool story bro, can we get back to how you were saying that stroking a penis while sexually aroused is not gay but sucking a penis while sexually aroused is gay?
Also: comparing us to primates is useless. 99% of the people that use evolutionary psychology of other species to explain human behavior simply lack better arguments.
Shows you have no knowledge on psychology but i can give you a pass on that one.
