Sex help /low libido/low sex drive

Okay so I’ve been dating this guy for 7 months now. I waited 60 days until we had sex (the goal was 90 days) but there was so much sexual tension, I was tempted so I let it happen. Now we’re at the point where we get tested together and we don’t wear condoms. Anyways, I wholeheartedly believe my libido is low, it has been low in the past and at times I went months without sex in the past without any issues. This guy sex drive is high so he’s expecting to have sex 3 times a week, because of my schedule I be so tired to have sex during some weeks, sometimes we have sex once-twice a week or none of at all . Usually we don’t have sex the week before and of my period because I have no interest. Right now as of today I am in the week before my period so I have no interest, last night I wanted to have sex but I was too tired and now today he’s at home and not with me but I just had the random urge to use my sex toy, I didn’t text him telling him I wanted to have sex because I was with him all day today and I’ll see him tomorrow and he lives 30 minutes away so didn’t want to bother him but now I’m worrying why did I use my toy when I could’ve called him? I don’t usually use my toy, I use it maybe once every other month and me and him NEVER for more than a week and half without sex but I do know how he feels about my low sex drive and we’re figuring it out. Am I attracted to him physically? Yes of course. I am attracted to him physically, mentally, emotionally, every aspect. And when we have sex my thoughts aren’t “I can’t wait to get this over with” so that’s my sign to myself that I enjoy it and him. Maybe I’m overthinking and this was just random
