when i caught my brother watching porn during his high school years, i gave him a pack of condoms and told hik to use it wisely...since then, he has been openly discussing with me the challenges that he and his gf has about sex.. they've been together for 10 years but never had any false alarms because they always protected themselves
I wouldn't recommend it if it was about giving those to a high schooler completely out of nowhere and without somehow letting the parents know (at least in secret, if necessary)... If this was a straight couple, he could just give them a safe sex or sex-ed leaflet for teens... BUUUUT... given I don't know if there are LGBTQ versions of those as readily available, and given that this wasn't exactly out of nowhere, since the old man (Tarou-san) had become Kirara's sort of "same-team confidant" and had also practically heard Kirara getting it on with his boyfriend already... then I do think giving him the condoms and lub after all that was the only sensible thing for him to do.
I thought the same, that it’s pretty irresponsible and sloppy for an adult to give a high schooler condoms and lubricant. But, I’d probably do the same because I also want to correct him and, if something crappy happens cause of sex, I’m partially at fault.
