Me and my boyfriend's sex life-- pleasseeee help me!?

We've been together for just over a year and we are SO happy together! We have so much fun when we're around each other, and we can have just as much fun out in public doing whatever than we do having sex. We didn't start having sex until about 3 months into the relationship, and since then we've been doing it literally every day of the week, more than once. I love it and so does he, but I feel like it's becoming a bit much.. I just don't think it's healthy for us in the long run. We've tried to cut back a few times before, but we always end up having sex by like the end of the day lol. I wanna cutback forreal this time, but I'm not sure how to bring it up without being too harsh or hurting his feelings. Whatcha think? Thanks!
