i was diagnosed with PTSD due to a sexual assault and sex, I personally believe, will ever be completely normal but I think with the right person who is willing to work through and is patient and understanding, it can. I have crying episodes and have feelings of being overwhelmed while in the act and i have to stop. I actually refrain from sex as much as possible now because it's so embarrassing when it happens. I have lost my sex drive completely as well. I am sure the reason why it has gotten to the point that it has is because I haven't done a lot of therapy. So i recommend doing therapy for years to come!!!
