Weak Orgasms with Vibrator

Has anyone had this issue? I even tried googling and nothing comes up...I feel like I’m the only one. I started on birth control and now I am having issues orgasming. I bought a vibrator to use during sex and the first time I used it, the orgasm was weak and the second time I didn’t even finish. It’s a bullet vibrator and has good reviews too online and has 10 settings. I thought maybe sex is too much of a distraction and I used it by myself twice just to see and both times it seemed to take forever and both were weak. I’m wondering if it’s the birth control? I started it in September and didn’t start having issues (came from oral every time) until January. So I’m thinking my birth control had time to regulate and now my hormone level is making it more difficult...anyone else experience this? It’s weird that oral and even hand gives better orgasms than a vibrator 🤷‍♀️
