Is it normal that my bf doesn't want to have sex with me

Ok I am 20 yrs old and my bf is 25 yrs old, we are both in great relationship and do understand each other well despite of our age gap. But one thing I hate about him is that whenever I really want to have sex with him, He doesn't really like because he was too tired, he also confessed that He was already fed up by sex but not to our relationship. Actually in our 2 yrs relationship we do it everyday sometimes every other day but only once. And honestly he can't really satisfy me enough in bed. Even there's a time that were both drunk and our bodies really getting hotter seems that its just nothing to him but me I really want to have sex. I am curious if it its normal to any guy. Take note my bf have more experienced than me in sex.
