<human>: I've been in a text-based RP community for about 5 or 6 years now, and it's my main online community. I've met my best friend through it, was introduced to my current career path, etc. It's important to me. The RP I specifically do is with existing characters in media, so it's essentially like writing collaborative fanfiction. Sometimes, it involves writing out sex scenes, for funsies or to advance a plot. This so *not* something I get off on, and it's not something that my writing partners get off on. It's just fanfic. 

I didn't have to worry about telling people I was dating when I started in the hobby, because I used to be super shy and had horrible self esteem. Within the last two years, I've actually been getting out there and dating, and I even had my first boyfriend last year. However, I have no idea how I bring this hobby up and explain it. It's not something I'm willing to give up- it's a very important community to me full of close friendships. But I also understand that some people might mistake this for cybering or some kind of infidelity, and I'm not sure how to proceed. 

This actually didn't come up in my last relationship- it was short and I never was able to bring it up. How should I bring this up in the future? When should it be brought up? Would you suggest a specific way to explain it?

Give me a shortened version of the text
<bot>: I like to write out fictional characters banging each other with people over the Internet sometimes, how do I tell someone I want date?
