PTSD & Sex (Help)

So a little over a year I was raped. Since I’ve had flashbacks and they’ll come and go and for a couple months they were gone but lately they’ve been coming back hard and I’ve been talking to my therapist and she wants to try a new therapy but I have to wait a few weeks before I see her again.

Thing is I my libido has been crazy low even since before the flashbacks picked up again and even when I’ve said I don’t need it my partner will still get me off with like toys and shit. I haven’t had it in me though to return the favor like I’ve tried but he could tell I’m not really feeling it and it just kills the whole drive. And that was before the flashbacks, now it’ll set me off like even if he’s not doing anything close to what happened it’ll come up randomly and then I end up having a meltdown for like a half an hour.

Guys I don’t know what to do, I don’t want to keep having to do this with him cuz it’s obviously taking a toll on him too and I hate seeing this happen all the time.

Any advice?
