I was forced into baseball; I backed out on the first day. I really despise ball sports. I always wanted to try gymnastics; but that was only reserved for girls.

What do you say?
That's not true, gymnastics is also for boys, haven't you heard the instruments in men's gymnastics? They are: Hoops, Pommel Horse, Horizontal Bar and Parallel Bars. Come on, you are free to do gymnastics, those who tell you that they are only for girls, are ignorant people who want everything to have its respective gender.
Artistic gymnastics is mixed, go ahead bro you can try it.

Thanks for the encouragement.
The incident I was referring to was back in the late 80s. But I am happy to say that those younger than me are being allowed and encouraged to freely express themselves from a young age.
