I cum blood??

So i masturbated with my not so officially sex toy, its just a bottle shaped like dick, sleek and small. There's no sharp object in the bottle, its totally small, short and smooth. Probably as short as my middle finger.
The thing is whenever i masturbated, my cum is always covered in blood. Yesterday was the worse, there was so much blood, even when i wear my underwear it looked like spotting. Today i tried using the same thing to masturabte and im still bleeding, but only a little bit.
Is this normal??? Im starting to get worried. This never happened before, even when i had sex with my boyfriend.
Please please please tell me the answer. Is this normal or do i have a super serious problem
