Advice?

I was raped on the Fourth of July 2019 by my boyfriend at the time. It was okay until it wasn’t. I’ve been scared to have sex since then. I’m afraid of the ptsd coming back and I freeze up. I’m just afraid. My friend recommended I get a dildo but I’m still just afraid. I never got help for the incident. I’ve only told my close two or three friends. But I want to have sex again but I’m just afraid and I don’t know what to do. Any ideas or thoughts. I’m open to anything.
