Weak orgasms, can I do something to make it better

I have had really weak orgasms probably for like the last year. Even when I use my vibrator it’s just weak and kinda disappointing after I finish. I remember having mind blowing orgasms and I miss it. Has anyone else experience this? Was their something you did to help or fix it?

If it matters I am 27 years old been with my partner for 11 years I know my body well and so does he..
