My 37F husband 40M has been sharing intimate photos with my ex-husband 42M. What do I do now?

Throw away since they both use reddit and we all know each others handles.

So I (37f), found photos of myself on my husbands (40m) phone that were screen shots from an intimate video I made with my ex-husband (42m).

I've been with my current husband for seven years and was married to my ex for 6 1/2 years.

I was on my husband's phone when I saw a telegram notification come up from my ex- husband that said "before I blew out her pussy and after"! I clicked on the notification (maybe I shouldn't have) and saw a before and after picture of when we were first married (I was a virgin when I got married). It had a side by side comparison of my (V) from when we first got married compared to when we made a video (that I asked him to delete during our divorce) that showed an upclose image of what it looked like after two kids. I didn't know the first picture existed.

I was completely shocked that he (ex) would be sending this to my current husband and wanted to contact him and I wanted to contact him and give him a piece of my mind.

Then out of habit I scrolled up to previous messages and noticed that my current husband was not just a recipient of messages like this, but also a contributor to them as well. I saw pictures and short videos that he sent to my ex that he had made during some of our intimate moments as well.

From what I could tell it was started from my current husband saying, well you may have popped her cherry but I have the pie and eat it all the time. He then sent a picture of us doing it doggy style and then it became a competition between the two of them sharing different photos and videos of me with each of them.

I don't know what to do. I'm completely blown away and embarrassed that this has even happened. We have such a good relationship between all of us and I feel like I've been just another sexual conquest for both of them. I'm afraid that if I bring it up it will jeopardize the relationship between all of us and ruin the dynamics that we've created to all be unified.

Help me.... I'm at a loss. What should I do?
