If a guy did this what does it mean

It probably means he doesn't want you to open the door.

He's using his other hand to put his dick back in

Why don't you just ask him why he's doing it? How are we supposed to know? Not every guy does that and not every one will do it for the same reason if they do. Some people might to it playfully, or to bully etc.

He's teasing you I think. I'm not a guy so I don't know for sure but this happened to me before and I did find out he was teasing me or flirting in a way. Again, I might be wrong.

He's never done that to any girl before

And you know that because you are with him 24/7?

It sounds like you want people to tell you he is flirting with you or something like that. If you like him then ask him about it don't rely on petty signals like that which he probably does do to other people when you aren't there. I've had many friends do it to me as a joke, male and female, meant nothing more than that.

He's messing with you. Nothing serious

Man was having a sick laugh blocking your way tho. Stab him.

Ohh lol 😂😂 flirting basically?

You're analysing the situation too much

I kno bad habit but what's ur opinion

Focus on yourself, a guy does nothing for you )))))))))

Well...
