Ex made a Comment on my Discharge ?

This is my first post here. I was going to post this in another ask reddit but I wasn’t sure if it would be against their rules so I put it here. Please let me know if there’s any rules I may have missed. I was really hoping to get some clarity on something that happened that still upsets me and has been effecting my sexuality.

The last time my now ex (male ) and I (female) had sex was after I had a surgery. I had healed and it was a couple months post but because of the surgery and the the condition it was for I had vaginal bleeding for a while. The bleeding had stopped but I still had brownish discharge, my ex understood this or so I thought, they knew I was already struggling and understood that it was happening and why it was happening and wore a condom.

However right after they said that I had covered him in “brown shit” and was grossed out and ran to shower. I dont remember the exact words but they were clearly incredibly disgusted by my discharge and it hurt then and now I feel so ashamed and embarrassed. It hurt me so much and now even months after I still feel hurt and feel so self conscious and feel like I’ll gross anyone out that I think I’ll just never have sex with anyone again.

Am I overreacting? Do people see discharge, especially discharge like this as gross? I don’t know if I’ll ever feel comfortable sharing myself with another person again after this.

Thanks for reading stay safe out there.
