My man getting off

Okay, i may be selfish but it sucks when we have sex and he gets off so fast. Sometimes he makes sure im well pleased about 40% of the time. He gets his and he is done. An goes to sleep, I think that's a problem, i feel both partners should be well taken care of by the end of the night. Not sure how to approach it an not sound needy.... tired of the love of my life being satisfied and im only getting 40%....
