My 12 year old has frequently mentioned various boys in y7 dry humping each other, tables, chairs for a laugh. He hates it. My y10 said loads of boys in her school frequently engaged in this and promptly showed me a WhatsApp of boys jumping on sleeping boys ( on a school trip) and dry humping on them ‘for a laugh’. All very common and seemingly no big deal. It all looks ‘rough and tumble’ and boys being silly but I don’t remember dry humping being a thing in the 90s. Is this really a ‘thing’? If it happened outside school it would potentially be a very serious matter.
