Seducing Your Man For Idiots: A Call For Advice 😭😅

So my fiance and I have been together two and a half years, engaged for 10 months, and I'm Stumped!!! He's the kind of guy who doesn't really care how I dress or how 'seductive' we are with each other, but I've noticed since school started we've had waaaaay less sex 😞 we used to be spontaneous and passionate nearly every night, and I understand School would definitely cause us to cut back, but it's been nearly two to three weeks since we've had sex, and it's not even due to work and school. We even had rare opportunities to get the house alone together twice in the same week!!! But each night he teased me and we got sexy, he'd stop and say 'I'm gonna play League of Legends for a while, but I'll finish you later 😉', and I'm stuck in bed ready for a great night I wind up not getting at all... this has happened twice in a row 😭 and he doesn't even want to do Morning sex because he feels it 'kills the mood to do it in the daylight' 😞

I feel really embarrassed asking if we're still on for sex because I feel like I'm some sort of addict, and it makes me feel insecure because I get scared I'll feel pushy towards him for sex and pressure him into only doing it to quiet me rather than because he wants it, too (which I know has never been the case because he's super sweet and an amazing listener, always reassuring me I wasn't pressuring him). But I still feel like we might be too 'used' to each other, only expecting the usual 😔 is there anything I'm doing wrong? Am I being too much for him to handle sexually? Is there anything I can do to seduce him better? I'm stuck 😭
