How many people have YOU slept with?
15? You have got to be kidding!? I grew up during the 1970s and 1980s before AIDS, so things were different. And the big question is would I tell a new partner my secret number, of course, it's 15! How'd I do? Would I be truthful? No. Not if the best number is 15.
So, I guess I would have to keep mum about the whole thing. Perhaps I could fall back on the old, "I don't kiss and tell" deflection?
