Long story short: I’m (24M) American, and I’m visiting my long-distance Romanian boyfriend for the first time soon. In Romania, most cars are manual - including all the ones owned by my boyfriend’s family (I’ll be staying with them). I’ve never driven a manual before. His dad told me he can give me a quick lesson, and that I’m welcome to use their cars if I want; otherwise, I can rent an automatic. I don’t have access to any manual cars here in the U.S. to practice on, so I’m not sure what to do.

Meh, you’re not going to hurt a modern manual with a learner. They’re not even likely to hurt the clutch.
Internals of a transmission are primarily made of 3 materials: brass, aluminum, and *hardened steel".
Aluminum is for shift forks, I can’t even imagine a way to break one.
Brass is for synchros, which can be worn by grinding - which isn’t really easy to make happen anymore, plus but it’s not like you’re gonna sit there and hold it while it’s grinding, you’ll release it quickly. The last car I remember having grinding issues was because they didn’t use a synchro for second gear so you got a short little growl if you didn’t shift “just so”. Last time I drove that car it had 250k on the odometer.
Hardened steel is for the gears themselves. And those things are beefy.
I’ve seen dragsters miss-shift on 1960’s gearboxes that weren’t built for 450hp/500lb torque, and they’ve survived it fine (I’ve also seen them fail the same way). A new driver in today’s cars just can’t do that kind of damage unless it’s intentional - and that would take some time.
