Boost drive and spice things up?

Any tips on boosting my sex drive? It’s been basically zero since having a baby two years ago. My hormones are fine and I’m not on any meds. I have an iud but my drive was like this before getting it too. When we do have sex I rarely enjoy it anymore, sometimes it hurts and I can’t orgasm so it’s been making me not want to do it. I hate feeling this way and not wanting it and I want to change it! I love my husband but I’m also a bi woman and lately have been thinking about women a lot too. Nothing would ever come of it but I wonder if this could be part of my problem too? So maybe any tips on spicing things up to make it more interesting to me would be great too
