New to the page. Want to go but to scared lol

What's the normal age range there? I'm 20 and have never been to playalinda but have been wanting to go for awhile now just scared cause I feel like itd be weird if a guy my age were there I feel like people my age dont go. I already know if I go I'll probably get hard and thats what I'm embarrassed about I don't want people to think I'm a creep cause I'm young.. If anyone has advice or would like to go with me so I'm not so nervous/scared message me
