How can i go back???

So I’ve always been proud to say i have a tight vagina and recently my boyfriend and i have been having a ton of sex. Like literally every other day. And the first time he was saying how tight i was and how good i felt and tonight he said I’m not as tight as i was before but he didn’t sound upset or anything. I really want to go back to being super tight so what can i do? Should we have less sex? Anyone please help!
