Long distance to living together- Sex Drive

Me and my boyfriend have recently moved in together after having a long distance relationship. While long distance, we would frequently visit each other and have sex like crazy (obviously lol).

We moved in together 3 months ago. Since moving in, my sex drive is almost completely gone. He thinks it's because i'm not as attracted to him, or the sex is bad which is not the case. A little over a month ago, I got off of hormonal birth control(nexplanon) and switched to IUD(paragard) to see if it would help, and so far there has been little to no change. I want to have sex with him, but at the same time it's the last thing i want (if that makes sense).

We tried switching things up by doing things like tying me up and candle wax which i loved, but it still doesn't motivate me to want to have sex more often. It's starting to affect our relationship....

Any advice, tips, tricks?? I want to get our love life back on track. ❤️
