Spicing things up

So my husband and I had a great sex life before we had our daughter (surprise surprise lol). We are both so tired when we see each other at the end of the day but both want more sex. It’s embarrassing but it’s almost a sexless marriage! How do we find the time to have some fun while our 3 year old is in the house other than when we go to bed as we are just too tired? I’ve become quite self conscious too so it’s mostly my husband who initiates sex but I did step out of my comfort zone and sent him nudes while he was at work yesterday and he couldn’t help himself by the time he got home we just did it in the kitchen 😆 I also want to give him a surprise blow job later after the little one goes to bed! Just need some more tips to spice things up!
