Hi, I've name changed for this, although I haven't posted for many years. My son is 14 and came out to us a bi last year; we were fine with it of course, although a bit surprised as it was out of the blue and he was already in a 'relationship' with a girl. She, and seemingly the majority of their friendship group, identify across the LGBTQ spectrum (par for the course in schools these days) and she/they are now non-binary but not out to her parents, who we don't know. They self harm and have mental health issues.
The 2 boys in the circle are now heavily interested in being 'Femboys'; dressing up and looking cute/non threatening for the girls. I'm 99% sure my son is CISgender, and I know teenage experimentation is normal. But I worry that this is being accompanied at such a young age by BDSM influenced language - him being 'sub' to his partners 'dom' etc, She's 13, he's 14 and I don't think it's appropriate to be looking at a lot of what, to me, are fetishistic images of teenage boys pretending to be female. I worry where this will lead. To me, it's part of the pornification of childhood and I find it borderline misogynistic.
I've tried to explain to him that there are ways of being male that don't involve being macho (I'd consider myself pretty gentle) but that being an ally to women and girls doesn't have to mean changing yourself. I do check his phone occasionally (hadn't for months until recently I became concerned about this relationship) and from their messages it looks like his partner is pushing for him to go further with cross dressing etc. despite the fact that they've only just started kissing. He is eager to please her, uses nauseatingly cutesy language to her alongside this sub/dom angle, but says that he 'worries about dysphoria'. He's excited to dress up for her. He's never shown any interest in this kind of thing, was never the kind of boy to dress in his Mum's clothes. He's not sporty, is gentle, but very much a boy. He knows I check his phone and that I'm worried about this relationship and all it entails.
I'm trying not to overreact as obviously his hormones are all over the shop, he's found a friendship group that he feels happy in, and if this is just playing around the way we used to I'd be OK with it. But the internet seems to bring about the connection from being a feminine boy to porn, BDSM imagery etc and it makes me deeply worried that 14 is way too young to be potentially setting a course for a lifetime of fetishism and unhealthy relationships.
Any thoughts welcome. There's not a lot about this particular subject from a parents perspective out there. I feel if I approach the 'partners' parents I'd be breaching their trust in my son, and potentially setting off a terrible chain of events. I just feel they're all messing around with things they're way too young to understand.
