Always horny?!?

So I’ve been dating my boyfriend for 8 months and around the 5th month when we started dating we started having sex. About a month after I lost my virginity I couldn’t stop thinking about sex and I still can’t!! Like I am always craving sex! The other day we had sex like 4 times in 2 hours. And I was still horny! It’s not that the sex is t great because it’s like mind blowing but I just always want more. I am also scared my boyfriend will be tired of me wanting sex even though he says he won’t be. Anyone else feel this way?
