Should You Know Who Your Partner Has Slept With? The Honest Truth

Do You Really Want to Know?

At some point in a relationship, the question sneaks in: "Should I ask my partner about their past?" Maybe you're just curious. Maybe a little jealous. Or maybe you're wondering if their past could affect your future together.

But here's the real question—do you actually want to know? And if you do, what are you hoping to gain from it? Let's break it down, because this topic can get messy real fast.

The Arguments FOR Knowing Your Partner’s Sexual History

1. Health and Safety: It’s Not Just About Feelings

This one is straightforward: sexual health matters. If your partner has had multiple partners or past experiences that might put them at risk, it’s fair to ask about their history from a health perspective.

What’s reasonable to ask?

• Have you ever had an STI?
• When was your last test?
• Do you always use protection?

What’s NOT necessary?

• Exact names of past partners (are you planning to call them?)
• The number of people they’ve been with (more on that later).

Honest talk: I once had a friend who didn’t ask these questions until AFTER sleeping with someone. She later found out they had never been tested. Lesson learned: your health comes first—ask if you need to!

2. Avoiding Unexpected Drama

Ever been blindsided by a past relationship popping up? Imagine you’re at a party and your partner’s ex is way too friendly—and you had no idea they used to sleep together.

Knowing at least the basics of your partner’s past relationships can help you avoid awkward moments. No need for a full-blown interrogation, but a heads-up about any major past relationships that might still be around? That’s fair.

The Arguments AGAINST Knowing Too Much

1. The Number Question – Do You Really Want to Go There?

"How many people have you been with?"

Oof. This question has ruined relationships before they even started.

Here’s the deal: unless their number is relevant to health risks (see point #1), it doesn’t matter. People attach way too much meaning to numbers. Whether it’s 1, 10, or 100, what actually matters is:

• Are they emotionally and physically present with YOU?
• Are they respectful and responsible in the relationship?
• Do they share the same values about sex and intimacy?

Real talk: If knowing their number will make you overthink things, don’t ask. Once you know, you can’t un-know it.

2. Jealousy and Overthinking Can Ruin a Good Thing

Let’s say you ask, and now you know. Then what?

• You start picturing them with their ex.
• You compare yourself to their past lovers.
• You feel insecure about not being “experienced” enough—or worry you’re “too experienced” compared to them.

This is where the mind games begin. The past is the past. If they chose you, you’re what matters now.

I once had a conversation with a friend who spiraled into anxiety after learning about his girlfriend’s past. The relationship suffered because he couldn't stop comparing himself. If it’s going to eat you alive, don’t open that door.

The Healthy Approach: What SHOULD You Ask?

1. Set Boundaries on the Conversation

Instead of diving into unnecessary details, focus on what actually matters:

• Health & safety: “Are you tested and healthy?”
• Emotional baggage: “Is there any past relationship I should be aware of?”
• Honest curiosity (without judgment): “What does sex and intimacy mean to you?”

These kinds of questions lead to healthy discussions, rather than uncomfortable or unnecessary comparisons.

2. Ask Yourself: Is This About Trust or Insecurity?

If you feel the urge to ask about their past, pause for a second. What’s driving that curiosity?

Red flag: If it’s coming from jealousy or insecurity, knowing the details won’t help—it’ll just make you obsess over them.

Green flag: If it’s about understanding them better and building trust, then approach it with openness (and without judgment).

The Bottom Line: Know What Matters, Let Go of the Rest

YES, you should know enough to protect your health and avoid surprises.
NO, you don’t need to know every name, number, or detail of their past.

The past is only relevant if it affects your present. If your partner is loyal, respectful, and
