Struggling with a swimming dilemma

Assalamu alaikum everyone, I’m in grade 12 and really want to join my school swim team. Up to now, I’d just practice alone with a shirt and shorts that kept my awrah covered, but on the team they might push for those tight athletic shorts or no shirt, which I’m not okay with. I know longer swim gear exists, but it’s nowhere in my country, and my dad’s done paying for my equipment. Also, practice times clash with salah-I’d have to miss prayers-and the team is mixed with both guys and girls, which isn’t right Islamically. I’ve trained two years just to get faster, hoping to join, but now I see all these limits. I feel stuck because writing about self-taught swimming on my university application sounds pointless without showing leadership or teamwork. It’d be my first real competitive team, so I could finally race, but I don’t want to cross Islamic guidelines. Universities ask about your passion-mine’s always been swimming-but I’ll have so little to say if I skip this. Applications might need references from club leaders too, and I was counting on the swim coach for that. Any tips would really mean a lot, jazakAllah khair.
