At the risk of being rude, I don't really see how "takes place on college campus" is an idea; it's more of a trope, really, and one that plenty of stories on this site already follow. The "stripper professor" thing is indeed an idea, and a fairly good one, but it's not yet a story - it could be amazing or terrible, depending on your writing skills. Your story needs to have engagement before other authors write to it. Ask yourself: why would people add to your story instead of simply writing their own?
In a CHYOA story idea, there is usually an intrinsically sexual element beyond, "Man fucks woman, then fucks another, then fucks another..." I'm afraid the mere thought of a co-ed dorm doesn't exactly get me all hot and bothered. Trust me, I've lived in one, and they're not as racy as they sound. That's not to say what you've got so far is bad, it's just that you need more substance before people can determine how interested they would be. That substance often comes in the form of writing.
TL;DR: As it stands, it sounds like you have less of a playground and more of an empty yard. Try building something first.
