My boyfriends sex drive is low, how can I bring it up?!

So I have a really high sex drive and my boyfriend does not. He recently told me that it’s starting to feel like a chore to have sex because I want it so much, because he would be happy with once every week or two. Any tips to bring up his sex drive??? I’m having a really hard time believing him when he tells me “I think your sexy and I love you, it’s not because I’m not attracted to you. I think your beautiful” and things like that because when we first met his sex drive was way higher than it is now. He thinks that is because he went so long without it. I’m honestly not sure, I just know he has mentioned trying testosterone boosters ect so I was curious as to what else might help.
