Help in the bedroom

So my husband wants the old me back. The one before 3 kids who use to give out BJs all the time and do all these amazing positions. I guess I’m not her anymore. I guess I’m boring. I get horny but my sex drive just isn’t there. I want to do more but I’m always so tired. I’m a stay at home and work from home mom of a 4,3 and 6 month old. I need some advice and tips. Sound I look into the female pill from the sex store? I need to keep him happy. I’ve been so exhausted lately that o don’t remember falling asleep.
