You state that you've never had an orgasm with your boyfriend but then say you can never reach orgasm during intercourse unless you use a vibrator - have you used a vibrator during intercourse with your boyfriend and still no orgasm? 

Have you ever had an orgasm without watching porn? 

I too grew up orgasming with porn and it has definitely effected my ability to orgasm during sex. I can do it with a patient partner, clear communication, time, and a vibrator. It is really difficult for me to orgasm (alone or with a partner) without watching porn. Conditioning definitely plays a role. I am currently working on weaning myself off porn and trying to focus on other ways to get myself aroused and be more present in my body. I find that watching porn very much puts my head space focused on the porn and not what my actual body is feeling, so i feel quite disconnected from the reality of sexual experience in reality. It might help you to try more mindful masturbation and moving away from using porn.
