You don't feel harmed because the harm being done to you is societally approved of. It checks the boxes of performative manhood. So, you don't think you're being emotionally harmed.
Yet look how men struggle with connecting, with communicating, with being embodied, with feeling heard, with feeling valued, etc.
All those things happen because of Patriarchy and sex is one of the main arenas it plays out in, where we reduce each other down to less than human.
I don't know of any research and frankly, I don't believe you could trust it anyway because such research is notorious for biases.
Let's put it like this. The presence of widespread maladaptive behaviors is an indicator that something is amiss.
When motherhood leads to widespread addiction, and we joke about "mom juice" because it's so well known a problem we ignore, then we know there's something wrong or off in how we're perceiving and going about motherhood.
I'll spare you....I could do a list of these all day. It boils down to: if there wasn't something off about the way the mantle of manhood is perceived and performed in regards to sex, there wouldn't be so very very many men who are such hot messes in regards to their sexual selves.
