Orgasm Help?

So, I was hesitant of posting this but I decided to go for it, my SO & I have been together for a little over 2 Years, when we first started having sex it was a little difficult to orgasm but I did often enough, nowadays it’s getting harder & harder to get there, it’s not that he doesn’t feel good because he does, it’s just I can’t get to that point & I end up faking it which I hate doing, does anyone have any tips or tricks to help me fix this? I don’t want to have to masturbate to get off afterwards all the time...and he feels like shit when I don’t orgasm...
