What is it with motherfucking sleepovers??? Do boys not do sleepovers? Like, are you telling me no boy has ever had a bunch of his friends stay over at his house?
Also, "recommendations of bras she's worn". You just know he jerks it to his mum's undies.
Boys absolutely have sleepovers. It's pretty common for most kids, barring really shitty home-lives. It's an important part of forging that 'best friend' relationship that most kids have.
They say 'sleepovers' in the sense of like teen dramas with lesbian porn overtones that they've convinced themselves female sleepovers are like. Never-mind that a lot of girls wouldn't have large sleepovers anyway because parents don't want that responsibility. Most teen girls will have MAYBE two others sleep over, but it's way more typical to just have the one- with special events, birthdays, being the exception. You have sleepovers with your best friends, because you trust them, and it's usually the two/three of you being idiots. It's not a lesbian party.
'Sleepovers' when you're an adult female are much the same, usually, although the vast majority will be if your friends are too drunk to get home most of the time. Adults appreciate their own beds and want to go to bed sooner, or are willing to go home way later, to really call long, into the night hangouts as adults, sleepovers.
imo. the bra thing is just mom being smart and OP being an idiot. If you take a male to get fitted for a bra you will have a big band with a tiny cup because there's no or barely any breast tissue but they have a bigger torso. It's not as simple as strolling into a bra shop and picking one off the rack because you're probably going to need a very odd fit. Frankly, I'm honestly surprised the troon hasn't gone and gotten themselves fitted multiple times, to subject multiple underpaid sales girls to having to cater to them and treat them like 'real women' at a fitting.
