My bf gets SO flustered when I kiss him and it's actually unhinged

Okay so my boyfriend gets embarrassed crazy easily, right? Like every time we do skinship his ears go BRIGHT RED. Like full crimson. His skin is pale so it shows even worse and honestly it's the cutest thing I've ever seen in my life.

So today I'm holding him and he smells so good, that sweet boyfriend smell, so I kiss his neck. And what does this man do. He buries his face in my shoulder and starts doing this little wiggle thing. I'm melting. I grab his face to kiss him properly and the boy is just standing there with his ears absolutely BLAZING red, both hands gripping my sleeve like his life depends on it, eyes squeezed shut, just... waiting. Not moving. Barely breathing.

How is he real. How do I have a boyfriend who does this.
