Not the typical question on here, but not sure where else to ask

So, I'm a writer, and I've wanted to branch into different forms and genres for a while to keep my mind fresh. Recently, I've been getting ideas for romance/erotica, something I've never written.
The problem: I haven't had many experiences, if you know what I mean...? And that's not a topic one can do a lot of research on? I'm not sure how to make such a story feel realistic. Any ideas or should I write something completely different?
