Is there something wrong with me?

Hello my fellow <a href="">eve</a> users. I have an issue. I can never finish during sex. 
I am able to masturbate and finish and whenever we're in the act, it feels great. I love it. But I am never able to reach my peak. I feel like I'm broken. 
Does anyone have any tips that I can try? Or maybe things that my partner can do to help me get there?
Thank you all so much 💕
