I was violated by someone who was supposed to protect me and my relationship with guys/men is ruined. How do I stop fearing guys?

I’m not going to no into detail but during the saddest point in my life someone who was supposed to protect me betrayed my trust and essentially groomed me. (this man was in his mid forties while I was 15) It’s been years now (I’m 19) but I’m scared of guys my age because I fear they’ll be cruel to me or overly sexual. Sex honestly scares me and I haven’t been able to get into a relationship because of a combination of those things. I can also be overly hostile or mean (ie I tend to glare if I think I guy is talking about me or looking at me) because I just get so scared (I’m not even sure of what at this point.) How can I get over this fear? Guys, how can I identify good safe men and make male friends? Girls, if you’ve been in a similar situation please reply or comment how you got better?
