Changing habits

I've used to feel like I was addicted to masturbating, I'd do it up to 2 or maybe 3 times a day and thought all day about getting home and doing it. I'd also always watch porn otherwise I wouldn't be able to get off. Over the time I reduced it to once everyday or every other day.

6 months ago I got into a relationship in which sex used to always go wrong and recently we've found a way for both of us to enjoy. I still have a really hard time orgasming and it's not nearly as intense as my masturbation orgasms even if it's a clitoral one in both cases.

Do you think watching porn may be the reason? I've been trying to masturbate without watching and only fantasizing with my partner and it really is more difficult to cum. Any tips on making reaching orgasm faster and giving up on excessive masturbation? I'd like to mostly have sex when possible instead of masturbating between sex sessions.
