The sex is bad

This is really embarrassing Bc I love my boyfriend and I can’t imagine myself with anyone else. But our sex is just bad. It lasts a total of 3 minutes. And every time it starts to get good and I start to enjoy it he pauses and we wait, Bc he has to cum and doesn’t want to. So then we start again and it’s like a big reset button. I haven’t had a orgasm in a year now 😕
