Okay, this is going to sound embarrassing. I am 15 years old and I'm not a virgin, but I only had sex with one guy who truly penetrated me. So this is what I've been doing about my non-virginity. I love to masturbate and watching porn. I can't lie about it. I masturbate with hair brush handles, a hammer, kitchen appliances(spatulas, big spoons), the curling iron(when it is not on) and just about anything that looks like it can fit. However, every time I do masturbate, there is always little to a lot of blood on them. I don't know what is wrong, but I need answers.

You are most likely damaging yourself by using items that will harm you. These items are used for other purposes and besides rips, tears and other damage there are infection issues also.
