I have that same issue. I have talked to my T about this. She has two suggestions. For me, half the time it is trigger related. But sometimes it is not. When it is not related to triggers it is tears of overloaded emotions. Positive ones. Joy, relief, release, connection, and contentment. She said she sometimes cry's after sex to. And that it is ok. I as glad to know she is a professional and does that to.

Her suggestion to me was to let my Husband know in advance what that crying means. (the kind that is not related to a trigger) He needs to know it is not something he has done, or sadness over the events taking place. We have also talked about what I need for him to do in the event that happens, which happens to be the same for when it is induced by a trigger or when it is positive. For me personally I need him to ignore it. It is just something that happens, and it is easier for me not to have attention called to it.

I do seem to be able to delay the crying until we are done most of the time. That is how he can tell the difference in a trigger or just emotional release. Durring sex (for me) it is always due to a trigger, sometimes after sex it could be either one, the trigger or emotional release.

Can you stop the tears, I mean delay them? If I can push myself to wait until we are done and he leaves the room that helps a lot. I totally understand that ball in your chest feeling. If I can mentally hang on to that ball until my H exits to room or until I exit the room then I can let it go or sometimes it even fades.
