You said he was objectified, by one woman once, not abused. By the time he’s a teenager he’s more than physically capable of objectifying her back, of protecting himself from any possible (& highly unlikely from an woman) assault and assaulting her himself. Even if he finds it upsetting to be objectified he is the one with all the power and he’s unlikely to come across much objectification from woman, and massively unlikely to be assaulted by them (in fact for a boy any actual threat -which is still highly unlikely- from a woman is most likely to come from their mother or primary female care giver).
For my teenage girls there’s no way they could fight off any male, including your son, and it’s highly likely they would walk straight out to be objectified or face other assaults from lots of other men, including your son.
Even if you are talking about actual sexual abuse, while any actual insistence of molestation is of course as traumatic as any other, the reality still is that the world we then live in effects how we heal (or don’t) after. Boys are much more likely to be believed, to see their abuser prosecuted and face longer prison terms. Other than very rare circumstances (say Michael Jackson’s victims, Cory Feldman) no one ever uses the term crying rape about a man coming forward about abuse and no one says they were asking for it. They are much less likely to be revictimised, where as it’s highly likely woman are. There’s way more charities and abuse survivors support taylored to male only help, much more money goes into nhs mental health help for men than it does women. Potential future partners are much less likely to be put off by a mans experience of abuse, or take advantage of it, yet us women are seen as damaged, or as shameful or as targets for abusive men. Men are seen as brave and hailed as hero’s for speaking up, us women get eye rolled and oh here we go again-ed. There’s also the basic biological reality that for any woman pentitrated by a male we have a much higher likelihood of catching stds/is (about 9 or 10 times more likely than a man catching it from us) and then there’s the risk of pregnancy, and the risk to our lives that carries, along with trying to deal with medical help for pregnancy after rape- whether choosing to abort or not.
There are other factors that can make coming forward, and therefore healing, difficult for male survivors- they almost always climax during assault (although this can happen to women also) and that tends to come with confusion and shame and a sense they might have consented on some level and on the rare occasions that it’s a woman assaulting a boy there tends to be a shame about the idea that a boy would be greatful for the sexual interest. So there can be other aspects that are difficult for male victims to process, but for the most part for any male victim healing from assault they are massively privileged by living in a world where they are the privileged class where as any woman survivor is trapped trying to process it in a world where they still face threats from every man they come into contact with.
It’s entirely different an experience, and like everyone has said it’s wrong for women to objectify men also, it’s completely different due to the hirachy of power that men have and we don’t. Again, claiming that it’s the same thing is the equivalent of shouting all lives matter in response to blm, or being colour blind to the reality that poc are oppressed based on their skin. Women are oppressed based on our bodies and men aren’t. You can’t be delusional about that on a feminism board.
