Masturbation orgasm

Sam

Okay so my last post was about my SO ejaculating too quickly now I come to find out he masturbated .. the same day right before we were to have sex and he ended up cumming literal droplets. I'm beyond furious About him masturbating and he told me it was to images of me and not porn supposedly but for some reason I'm just mad that he did it in the first place. He said its because I said he's cumming too quick. But idk why it's bothering me so much that I'm upset and in tears and want to rip his brains out at the same time I'm angry idk why
