1. Don't tell us what it is, but do you have a sexual secret you have never told anyone?
Of course I do.
2. Do you have a nonsexual secret you have never told anyone?
Probably, but I can't think of it.
3. Did you ever tell someone a secret only to have them spill it? What were the repercussions?
I can't recall an incident like that. It's probably happened to me at one point, it seems to happen to lots of people.
4. Did you ever spill a secret someone told you? What were the repercussions?
See my previous answer.
5. Tell us a secret someone told you, however long ago, that you've never told. (You can disguise names or details.)
If I could remember any secrets, I would tell you one.
