How to help my man?

I need help!

Every women wants a man that can last a long time during sex. I thought I had found that. I know sex shouldn’t be a big part of the relationship but it is.. I’ve found that I’ve been able to connect with the person in a much deeper level when we have great sex. I’ve had great sex with my boyfriend but over the past month he has been cumming way too fast, to the point that I do not get to enjoy the sex as much. To be honest it bother me a lot! So I want to know if there is anyway I can do things to help him last a little longer so that it is more enjoyable for the both of us and not just for him.
