Boyfriend sharing room with other girl

So my (22f) boyfriend (22m) of 3 years is going on a uni tour, and he's been put in a hotel room with a girl for 12
nights. I don't know this girl, but I have staked her social media, and she is so gorgeous (massive breasts too, which she isn't too bothered about covering up...I barely fill an a cup...haha big insecurity of mine). These trips are also well known for being extremely boozy with clubbing every night. now, I'll just make it clear that I trust him 100%, we've lived together for 2 years now, and without sounding silly, I'd be extremely surprised if we don't end up getting married one day. I am sure no funny business will go down, but I still feel kind of weird about it? I don't know this girl and I don't want him seeing her after a shower in her towel and stuff like that. Is this crazy? I feel like I at least want to ask him not to drink alcohol during the trip(or at the very least keep it to one drink a day). Is this mad and controlling or me, or is it reasonable? I mean, ideally I'd want him moved to a room and share with another guy, but he doesn't want to kick up a fuss because he doesn't know the students that are organising the whole thing. Any advise would be greatly appreciated. Sorry it's long haha

do his parents know about you?

For all the people talking about cheating, he really wouldn't, that's not a concern of mine. I mean, it took until the 6 month mark in our relationship before he was ready to have sex as it takes him a while to be comfortable.my main question is if I am justified feeling a bit uncomfortable, even though I know there won't be any funny business happening

I think it’s weird to share a room with a stranger of the opposite sex. I would find it uncomfortable enough to share a room with a random girl.

Wait, you're a guy?? Somehow I'd always imagined you as a girl - I thought Yalia was a girl's name.

I am a girl. I wouldn’t want to share with a guy because sharing with a random female would be weird enough.

Yes this arrangement is weird. Why would he be put in a room with a girl? Are they friends? If not I would absolutely say you are not happy with the room situation.

If you know he wouldn't cheat, why else would you be feeling uncomfortable? If its the fact u might think she might try it on him, that's a different story..

Is this for real?
