Trigger warning: needing advice, how to be intimate again.

I’ve been diagnosed with PTSD for about 4 years now (related to sexual abuse in my childhood and being raped in my late teens). I am now happily married to a man who I truly love and would never hurt me. I’ve always struggled being intimate, and although my husband never holds it against me I know he wants to have sex more. I have a lot of anxiety around it, so we almost never do it. I can do it around 1 time a month if that. I’ve been dealing with this for YEARS. I have my good times and bad. Unfortunately I’m stuck in the bad right now, and don’t know how to make myself comfortable with sex again. My husband is so patient and kind but it’s hurting me knowing I can’t give him that. Please any advice?
