Advice, tips, & suggestions would be appreciated!

So backstory... im 21, my husbands 22. We have a 2 1/2 year old & a newborn. He is a pipeline welder, works about 3 hours from home, & gets very little off days (like 2 to 4 days a month). So he's rarely home. I've sent him pics while I was still prego, just of my chest. I kept some things covered, in attempt to make it sexier. Anyways, since baby #2 has arrived, I have no idea what to do. My boobs are far from desirable since I've been breastfeeding, but I still want to tease & flirt with my husband in some way. I would try butt pics, but no joke, I have no ass... like at all. I've tired asking him what he'd like for me to send, but he always tells me "Anything of you will make me happy", so he's no help. Help please!!
