all d*cks FLOAT IN WATER?

I was taking a romantic bubble bath with my man. We weren't doing anything sexual, just enjoying eachother. 
And the bubbles died down and before I put more in...I noticed something. 
His dick is like floating upwards. I stop everything just to stare at his dick like 🤔 and I just keep leaning in closer to the water and I touched it like ???. Legit didn't even say anything to him, I was trying to figure out for myself lmao 
And he's like "can I help you?" 
And I was like "your dick is soft and it's floating" and he's like "yeah, pretty sure everyone's dick floats though" 
And I was like no, im going to Google this. I was right. It says "get Into a body of water, but face down this time" 
Like, you want me to fucking drown my SO lmao oh my god. This is what happens when you date a weirdo who questions everything hahahahaha 
Male anatomy is so strange
