A little background: my girlfriend and I have been dating for a few months and I’ve known her for a very long time. Our relationship became serious a few months ago and we decided to make it official. She’s currently going to school so it’s sort of a long distance thing but it’s only an hr and a half away so we see each other frequently.

Now I know she’s into lesbian porn and she doesn’t really like to talk about it but occasionally she’ll open up about it. Last night her and I were talking and she slipped up about having a tinder while she was away at school. This made me upset because the whole time she’s been away at school we’ve been together. She later on admitted that it was to meet girls. Not to necessarily hook up but to chat and talk dirty I guess but she was pretty hesitant to talk about it.
I really don’t mind that she is into it and I actually really like it. I tried to reassure her and make her understand that I was fully behind her but she said she was really uncomfortable talking about it. How do I get her to open up?

Thanks
