hi this is a bit embarrassing but i’m 13. i always hear my friends talking about masturbation and how good it feels but i’m too shy to ask them how to do it. they alwaysssss talk about how nice it is and i feel a bit left out. also, is it okay to be doing this at 13? sometimes i feel like i really really need to touch myself but i dont know how to and it gets frustrating. can someone please help?
