My little brother uses my room to chill in when he comes home from school (which I have no problem with) but every time I get into bed after getting home from work, my blankets are always covered in clear, sticky shit. I'm a man myself so I know what that shit is, or atleast that's what I think it is but I don't want to embarrass him as he's at the age where that shit starts and I don't want any awkwardness between us but I'm genuinely angry that almost everyday since he started puberty, I've come home to fucked up blankets. What do I do and how do I even approach this? This is a genuine concern btw, I've literally never had this problem before nor did I ever do this shit when I first went through puberty.
