How do you block a number on the iPhone?

How to block a number from iPhone and is it free? ?

• There is a guy who I met. He was feeling really down about his life and was saying he was going to kill himself. I gave him my number because I'm a very caring person and I didn't want to see him hurting himself. Although I have never put myself "out there" he always asks for me to sext him, send pictures, go to my room to have phone sex, etc. I always tell him no and then he says he is never going to talk to me again. The next day I'll wake up to at least four missed calls and then he'll text me like nothing happened. He knows I have been raped, and one night he called me on restricted. I was having a panic attack (I was having flashbacks) and he was like "I might as well just come over and rape you" because he was talking about sex. I've literally had enough. I told him I was with family for my uncle's funeral and he texted me like "can i come shove my _____ up your butt?" wow. I need to know how to block his number and is it free?

• Answer:

  Tell the police or something. This is sexual harassment, and he obviously needs help.
