<human>: I met a girl through Tinder about six weeks ago, and since then we've been on 10 dates over the last 6 weeks. I asked her about being exclusive a little over two weeks ago and she agreed. We did not talk about calling each other boyfriend/girlfriend however, so I'm not totally sure what I'm supposed to do with regards to that.

I understand many people would say it's childish to worry about it and that it doesn't matter, but recently there have been several situations in which I've been unsure how to respond. For instance, I was hanging out with some friends and one of them happened to mention that this girl and I are now exclusive, to which another friend responded "oh so is she your girlfriend now?" I hesitated for a second because I realized that I wouldn't want to go around calling her my girlfriend if she wasn't ready for that, but I also didn't want to give the impression to my friends that I'm unsure of my feelings about her. I ended up reiterating that we were exclusive and said that we hadn't talked about labels though, to which my friend responded "oh I didn't know there was a difference."

So what of it? Should I talk to this girl about calling each other girlfriend/boyfriend? If so how should I do it? Is it perhaps still too soon?
 
Another thing that may be worth mentioning is that about a week before we became exclusive, she told me about how when she was waiting for the subway one day, some random guy kept harassing her telling her "you need a boyfriend." Might have been just something that happened, or maybe it was a hint?
