Sensitive topic

When I was younger I was molested and he basically forced me to suck his dick. Growing up I always thought I was gay because after that experience men scared me.

A few months ago I finally got with a boy, I immediately connected with him. He’s my best friend and my favorite person. I trusted him enough to be able to have sex with him. My boyfriend wants me to suck his dick but I’m so scared to. I start thinking of what happened when I was little and I start to panic. I’m scared one day he’ll get mad and just leave me. I haven’t told him what happened, I don’t know how to.

(I’m posting this in many groups to see how any other girl would go about this or to get their advice)
