Little sex

Me and my boyfriend have been together for a year and when everything started up we were both going back to school so i only seen him weekends and the sex would be so hot and we literally couldn’t get off eachother. Now that it’s summer and we see eachother a bit more, the sex has stopped like sometimes we go one week without anything. I’m a young girl in her 20’s so my drive is super high atm, but he’s not feeling the same way. Can anyone give me some advice or even some ways to spice things back up? We aren’t unhappy at all, everything besides in the bedroom is amazing
