love life problems-please help!

Kira
Okay so I've been talking to this guy for over two weeks now about and I guess we've been kind of flirting and this past week we kissed (pecked) a bit and he's really sweet and cute but then he asked me out and started calling me his girlfriend. I'm not really comfortable with the label cuz we haven't even gone out yet and I feel like he doesn't really know me that well and I'm still not quite sure how I feel about him. I was down for casual dating and seeing where that went but now idk. 
Thoughts? Advice?
Anything is appreciated,thank you!
