My boyfriend randomly said this and I couldn't stop laughing

After we'd done the deed, we showered and got dressed and ran errands as usual. Hours later, in the store, he remarked at how surprised he was that we've had sex the entire 9 months. He seemed genuinely surprised and proud at the same time. Idk why but I couldn't stop laughing. I was like um...thanks? I guess it's amusing and kinda cool that even at 36+4 weeks, with a 7 pound baby in between us, tons of stretch marks and random vomit incidents later, he still gets turned on just from hugging me. 🙄😂 Let's see how he feels after watching his big headed daughter come out 😂
