Can’t seem to finish…

So when I was 18 I was sexually abused by my boss for about 7-8 months. There was never sex but it was mainly show him my boobs, my ass, sending pictures and videos, getting fingered because my job was threatened and I needed it to remain living at my parents house. I’ve moved on from that job and have been going to college to get my bachelors. I’ve met this amazing guy who I honestly believe could be my soulmate. We’ve tried to be intimate but I keep having flashbacks from the times of my boss and a few guys I’ve been with before this man I could never cum. I haven’t had a guy make me cum in years, most try so hard but it just either hurts or I just can’t do it. I feel like I’m disappointing and not like a full woman. I can make myself cum and usually use a vibrator but i’d like to have that special moment with my boyfriend too. He keeps reassuring me it’s okay but I don’t eventually want him to become dissatisfied. When I let this all out to him he told me he’d do some research and see if he could find some things for us to give a try just to see. I also am reaching out for help but not entirely sure where to go so I thought you ladies would be of help. Any ideas, thoughts or suggestions?
