<human>: I feel like such a scumbag but I think I need to be honest about my feelings instead of pretending I don't have them.

So I met this girl online about 2 months ago and we hit it off. She lives about an hour east of me. I lost my virginity to her. Later, she asks if she I want to be her boyfriend. I am really bad at saying no so I say yes. I really don't see the point in being her boyfriend, though. We live too far away to spend a whole bunch of time together. We are already really good friends who are having sex. What is to be gained from this? 

She also isn't as kinky as I am. I don't hold that against her but it would be nice if we weren't exclusive so I could explore my kinky side with other people.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Do I break up with her? Ask to back to being FWB? Ask for an open relationship? How do I go about these things?
