Having a hard time orgasming with new partner

Hey all. I recently got a new man after a 6 year relationship. Me and my new boy have been together 5 months now.

With my bf of 6 years, I was able to orgasm but it had taken me about 2 years to discover and learn how to with him. But after that it was everytime.

Now that I’m with my new man, I want to so bad and I know I should be able to but I just can’t.

My ex would complain that I was bending it alittle when grinding and trying to O and it was uncomfortable so I’m worried I’m doing that to this guy and that doesn’t help the situation.
