IS MY BF A SEX ADDICT?

I'm 21 and my boyfriend is 26 years old. We have been dating for a year, we moved in together 6 moths ago. At first we were having a lot of sex, about 6-7 times a day and I really enjoined it. But not so much anymore. I tell him that I would fine with doing it 1-2 times a day but he wants more. He's always in the mood for sex, if I touch, kiss him or hug him he right away wants sex or wants to go down on me and if I refuse to have sex he gets upset. He tells me that is because he loves me. I'm getting to the point where I don't even want to do it all, I'm not even getting wet anymore! is it because we do it so much? is he a sex addict or is this normal because we are young? please help!
