Would it be weird to enroll...

In an adult women’s beginner swim class? I really want to learn how to swim. I took swim lessons when I was 5 to about 7 years old, but then it wasn’t required anymore. I don’t even know if they have adult beginner swimming classes. I love the pool so much, but I am not a strong swimmer.
I think I would really enjoy it. I hated it as a kid mostly because we had to wear those horrible bathing caps back in the 70’s.
