SO told me hes bored of our sex

This just started happening a little over a week ahi, only weve been together 8 months. I still have sex drive and am down for it but he isn’t and told me today hes bored of it. And then proceeded to say we shouldnt spend so much time together, usually 5 days a week is what we do and not all day. Felt pretty shitty to hear and also dont know what to do. Weve been buying ballgags and I already had handcuffs and wip and he got a few more toys we can use coming in the mail, but i feel like hes bored of me. Ive tried all the things, i initiate and do what he loves but its apparently boring. Idkkkk. We used to have such greattttt passionate love making that made me

Ive asked if he wants to see other people and if hes not attracted to me anymore, he hesitates but disagrees and says im beautiful . I dont know what to do. Im definitely in love with him but i feel he is falling out of it with me.
