Help me surprise my husband!

So I haven't ever been the most sexual person. I've only had 2 partners in my life, one of them being my husband. I've been wanting sex even less since I got pregnant but lately I've been wanting it soooo bad that it wakes me up at night. I dont want to just go up to my husband and be like let's have sex now lol so what are some really sexy ways to let him know I want a good time 😂😂 I'm asking anywhere from how should I make myself look to things I should do. Or maybe even things I could text him since he's currently at work. Just anything to spice it up and make it fun for him since we've only done it like 3 times in the past 4 months.
