What does he mean by he’s curious?

[rach27]

I have been seeing this guy for a couple of weeks now, and I have brought up the idea of a relationship with him, and when I bring the idea of relationship to him. He says he’s curious. What does that response from him mean?

[ohsheeT]

It could actually mean anything me. I am a person of curiosity. I'm curious about everything because I want to understand everything.
So, it could mean anything?

That is a question for him, but I assume he is interested in seeing how a more serious relationship would go.

Translation... You are attractive enough to consider sexy time but he's not that into you.

[Paige90]

It means he wants to suck a dick

[seeyounexttuesday]

It means he's not that into you.

Just want some fun!
