Tmi but also anyone have a similiar experience?

So me and my boyfriend are getting into it, I just finished my period about a week and a half ago so my vagina is still in the process of cleaning itself out right? Well halfway through i guess I had some discharge and he starts freaking out, which is understandable, but then he goes off and starts blaming me for “this nasty stuff” and it really hurt my feelings. Killed the mood entirely and I cried. He later apologized but my feelings were definitely hurt that he would get so angry.

Moral of the story, it wouldn’t kill guys to pick up an anatomy book every once in a fucking while to realize these things are normal and we have no control over when our vaginas decide to clean house.
