How to regain intimacy after baby?

Caitlin

So when my.fiance and I started dating we were all over each other. When we moved in our sex life went down bc I guess we just got too comfortable with each other and we didn't have to try so hard. Then I got pregnant with our little girl. Sex life was pretty much non existent. Well fast forward to now being 3 months postpartum my sex drive has gone up but I've been way more insecure about my body. The other day I tried to spice things up by sending him a picture of me and my new bra with the caption; I know you've been super stressed.. maybe this will help 😉👉🍆😋 Why I was so nervous I have no clue but he screenshotted the pictures but said he never saw the caption so I got frustrated and we literally had a mini argument. Yall how do I keep things alive when I feel like I shouldn't even try 🤣🤣

Advice, tips or tricks would be greatly appreciated!
