Orgasm Help

I've noticed recently that I've been having g a hard time reaching orgasm when having sex with my boyfriend. The sex feels great, I just can't get myself to finish as easily (or at all sometimes) as it was previously in our relationship. I've also found that I can get myself to orgasm very easily alone while masturbating. It's starting to become frustrating for both of us & he's starting to think that he can't get me off or get the job done like he used to.

I orgasm from clitoral stimulation 99% of the time, and I do have a vibrator that I bring into the bedroom frequently.

Any advice or tips would be greatly appreciated!
