My partner had sex with 60 plus guys. I want to know about it, how and why? It is not out of jealousy but of honest curiosity. I think she doesn’t share the honest truth. Is it wrong to keep asking her about this?

Yes, it is wrong to keep asking her about this.

You already know the rough estimate. What you need to ask yourself is why it seems to matter to you so much.

If you don’t trust your partner, the number of people she has or hasn’t slept with isn’t the problem. What are you afraid of? She’s with you for as long as she wants to be.

Sorry, but non-jealous partners trust their significant others. Jealousy and resentment on your behalf are excellent methods to quickly make her your ex-partner. Thinking that you are unworthy of your partner’s high regard (which is what you do when you don’t trust them) is a horrible way to treat yourself and your sweetie. You’re basically saying about yourself that you aren’t lovable enough as you are and have to prevent her from meeting someone else you think she’ll leave you for. In other words, you’re accusing her of having shitty judgement when it comes to choosing lovers. Not cool.

Work on your insecurities and being a trusting and loving human being. All the best.
