Bringing up previous sexual history

[SexShamed]

Sometimes when me and my DH get into disagreements, he brings up something I told him about that happened in the past between me and a past bf which involved me, my bf and another guy where something happened sexually, it feels like he’s shaming me. Is he jealous? Or maybe he’s using it as a personal attack against me.

You will only find out by asking

Well he's either jealous of trying to shame you for your past. Neither is healthy.

I would never ask my DW about her previous sexusl partners. She knows about one of mine, my ex wife, she does not know any details but has never asked about any others and I wouldn't ask her about her previous partners
What matters is that we are happy together, we leave the past in the past

We all have a past.

My wife and I each know about each others.

Not full numbers but some understanding and some intimate details.
