Help! Teen son's sexual confusion re: anime

I'd try blocking 'futa' and 'hentai' keywords on my home network for a start.

He’s 14. He should not be looking at porn, anime or otherwise. It might be internet control time.
Conversations about how you’re fine with him being gay if he should so happen to be in the end can be had. It’s easy enough for refer casually to his future wife or husband to make it clear you are not bothered either way.

Anime porn is a bit weird and I think you're right to be concerned about what he's looking at. 14 is an impressionable age.

There isn't a typical gay male.
Have you never spoken with your son about sexuality? It's a bit after the event now, but I do sometimes wonder why parents don't reassure their kids about their love and support before it's an issue (not saying you haven't OP but it's a major source of angst amongst some of DD's friends).
You're possibly overthinking this. He won't become gay if he's not actually gay
Cartoon porn is perhaps a reflection that he is becoming aware of sexual feelings but isn't ready to experience that with actual people yet?
Maybe a light conversation around porn use generally might be appropriate if you haven't broached that before? Would he be embarrassed by you talking to him - is his Dad around?

Link is discussed in my house regularly by all the kids because they love playing Zelda and they all want to be Link. Link looks like Peter Pan.
What’s distressing is that almost immediately he’s been groomed with the porn and it’s going to distort what he’s into... the anime and it’s more disturbing brother Hentai will often depict sex that has nothing to do with actual people but has the most contorted manifestations of it. Appalling if you are a malleable child.

Having a crush on an animated character at that age is also a sigh of immaturity and it’s this that makes them also vulnerable to the suggestive nature of the material being pushed at him. In all likelihood he doesn’t fancy Link, he just wants to BE Link and can’t stop thinking about him.

I think the narrative of boycrush and girlcrush has long been a way that people are defining the people they admire rather than actually want to have sex with.

Personally I would say to him that I’ve seen the material if it’s on your computer and having a frank and honest conversation about what is going on. Exploring his sexuality is fine and to be expected but I would be very clear about saying that when the porn is distorted like with anime, it’s confusing and not necessarily accurate to who he is. Sure he may turn out to be gay or bi but even then the kind of porn that he’s seeing isn’t going to give him a realistic expectation of women or men.

Talking about anime characters in a sexual way seems to be pushed on kids as part of this drive to desecrate their childhoods. One of my kids was told by her friends to talk about her favourite game characters in sexual ways and I was shocked when she was referring to her doll of this character as being “hot” and “my wife” when she was eight. This was the influence of the group of girls who are now all declaring themselves as gay men, confused anime porn soaked children.

Get internet blocks on ASAP. While he’s under your roof what he’s looking at can be monitored and filtered out. This includes his phone.

So does he know that you have an inkling? A lot of teens are ‘confused’ about their sexuality (thats as old as time) but these days the ‘advice’ they get online is just bonkers.
