Do you think it’s a good idea to find out how many sexual partners the person you’re dating has had? If the answer is “yes,” when in the relationship is the best time to ask?—LL, Los Angeles, CA

If you're comfortable offering up your number and if it's something you really care to know, then sure, ask him, but if you're just curious I say don't bother — it'll only fuel the jealous fire. Now with that said, it's imperative that you have a chat about your sexual past regarding health concerns before becoming intimate, get tested together, discuss birth-control options, and ask if he has ever engaged in risky behavior that could potentially put you in harm's way.
What's in the past is there for a reason, and truth be told, most people lie about their number anyway so I say why open that can of worms? Honesty and trust is what's really important when it comes to relationships, not how many people he has been with before you.
Though we all had pretty much the same take on this question, I'm with you Chris Kennedy — make love not war!!
