What are some activities that involve alot of boys that girls can join?

okk so i want more guy friends ( and a boyfriend, but friends first!!) there aren't alot of guys in my school, its basically an all-girls school lol. i want to join some activities mayb outside of school that involve alot of guys so that i can get used to talking to guys (i'm really shy and im trying to force myself out of it) and possibly make some guy friends!! i'm in manhattan, NY if there are any specific activities anyone knows of here btw :D
