Yes

Izuku breathes a sigh of relief at the experience being over and just casually floats in the water. Although for some reason he feels as if something is missing. Feeling the sensation of water over his bare ass and groin, a look of panic came on his face, praying to whatever deity above is listening that he is wrong as he slowly looks down and notices that his trunks were gone.

His face turns crimson red and he shrieks and he quickly puts his hands over his crotch to hide his penis. He quickly looks and around swimming around and looks for his bathing suit only to prove unsuccessful. Horror etches on Midoriya’s face as he unable to find them. Midoriya mentally thinks (Crap crap crap! My trunks are gone and I’m naked! What do I do?! I have to get back to my bag and get to my clothes. But how do I do that without anyone noticing?)

Midoriya looks at the beach and sees that a lot people are either sunbathing, playing in the sand, sleeping, or just looking at their phones. Deku realizes that he can use this opportunity to get to his bag and retrieve his clothes while everyones distracted, as well as use some sand castles, beach chairs, and umbrellas as cover. Is it risky? Yes, but what choice does he have, he can’t just stay in water until everyone leaves that would take way too long and might lose his window of opportunity. He mentally steels himself and slowly swims back to the beach preparing to put his plan into motion.

(Btw instead of sph, I plan to do something different with midoriya where he ends up in a kinky situation. I hope the auhtor doesn’t mind and hope it’s not against the rules or something.)
