Boyfriend lied about cumming? TMI but i need some advice on this..

About a month ago we were having sex, and my boyfriend doesn't last that long so it was already weird. He had a tooth pulled , and had perks. And that can make it harder for a man to ejaculate. But the next day we had sex again. And I don't think he took any perks.

I asked if he came, he said yeah. So I went to bed. The next morning when I woke up, and went pee. There was no cum in the toilet. So that would mean that he lied about cumming....

So if that's not the lowest blow for a woman idk what is. What does this mean? That I went from Kim K in his eyes, to Ellen Degeneres?? 😩 FML
