high sex drive

ok yall... I hadn't noticed this until my SO pointed it out but I've been wanting sex like crazy! until a couple of months ago I was never in "the mood" and had to have foreplay to even consider sex - but now I want it 5/6 times a day and I don't know why! I thought maybe it was just pre period hormones and all but it's all month long!! my SO is talking about how tired it makes him (so ive started doing all the work if you know what I mean 😉) and we still do it 5/6 times. of course after im tired and my legs feel like noodles but I'm just wondering if someone can shed some like on why my sex drive has done a sudden 180 🤔
