TRIGGER WARNING: explained rap situation

So back in October I was raped by a guy friend of mine. At first I did want to pursue a sexual relationship with me but the first night we were about to get into it I was under the influence and tired so I tried to sleep. He then proceeded to finger me to the point it hurt and then choked me until I was unconscious. I was so in shock I just laid there, it wasn’t until he put my underwear in my mouth that I started crying I couldn’t do it. I made him leave but he tried talking to me multiple times afterwards and I just couldn’t do it. I’ve engaged in other sexual activities since it’s happened and I’ve gotten better about the flashbacks and stuff but as soon as someone goes to put their hands at my neck I basically melt and the moments ruined for me. Will this eventually go away? I’m in a relationship with just the greatest guy and he knows the whole situation so he’s been an amazing support system but I feel like this last leg I have to work on with myself. Does anyone have tips?
