Wow, a lot of patronising posts today!
If that's the theme of the day, I can patronize right back. I joined MN when I was 21, after getting bored of sites aimed at my own age group, because I didn't like being in the same sites as young teens any more. I know all about this stuff, because I was helpfully educated on it all by older male members back in the day. Yes, since you ask, it does creep me out now that there were so many men online (in their 30s and 40s!) who were urging teenage me and my friends to explore whether our real life sexual explorations should include fetishes. But when you're 15 - 18, you don't easily realise how boring teenage conversation is to healthy adults in their 30s and 40s. I only started to reassess how genuinely fascinating any of us could have been to such older men when I outgrew the sites myself. In the years since, I've thought about the topics the then adults had been most active on. They were not performing a necessary public service when they wrote their 2000-word OPs on particular niche sexual interests. None of us needed to be educated on it.
But educated we were. I've had a look at the video. It is fetishwear, bought from specialist suppliers (perhaps etsy, perhaps a larger store), marketed as fetishwear.
Ikea on a Sunday is a cross-generational social environment. If you go there in your fetish gear, that is because the behaviour of someone in your group has escalated to the point that dressing up in private is no longer exciting. I say someone, because the reality is it may only be one of the three who wants to do this.
Moreover, going outside per se isn't enough either. This isn't the garden that they're in. Nor is it a specialist club environment amongst like-minded people. That's not exciting enough.
Someone there needs them to go out where other people, who are not in the scene, including children, will see the group. "Educating children" may even have been one of the justifications, by the way.
This is a moral line being crossed. I do not care if the audience (including children) present had no idea what was going on. Are we to wait until the quest for excitement progresses to the next stage after this one? That would be the stage where they make it clear to at least some of the people present that this is a sexual fetish.
It's a line: you do not wear fetish gear to places where children will see it. No, not even if you are sure none of them will realise. You know what it is and you shouldn't want to wear it around kids, because you shouldn't want to engage in sexual behaviour around children. The presence of children should be a turn-off.
If the presence of children is something you want when you are engaged in sexual behaviour, that is abhorrent.
When we see people in fetishwear in public, we should be aware that it is probably the precursor to sexual activity later in the day, and that the group are making memories for later masturbation. They are going to be thinking about an experience that included being being seen by children. It's not healthy to build associations between your orgasm and the presence of children, ever.
Just Say No to people in fetishwear in public.
