sex life

Is it normal as a 23/23 year old couple to only have sex around 3 times a month 🙄 its killing me. we used to have sex everyday last year and it slowly just dwindled to maybe once a week maybe once every two weeks. He just says he doesn't have a sex drive anymore. I'm like ok I'm still 22, I still need sex in my life! I see all these girls on here talking about how they have sex multiple times A DAY. Tell me I'm not alone.
