using a hair brush?

I recently tried using a hair brush as a dildo. It hurt like hell. Let me start off by saying I was properly lubricated and extremely horny. Anyways, I put it in and tried moving it and it would barely go in and that hurt enough. And then when I did get it to go in, it felt as if it was stabbing everything inside of me. You know how there are like a bunch of different intestine feeling things in your vagina, well it felt like the brush was just hitting all of that and it hurt so bad it even felt like my stomach was hurting, and it felt like I had extremely bad period cramps for about two days after. How does anyone find this pleasurable?? The plastic is so hard and hurts so bad. Is this what a penis feels like? I'm afraid that I won't be able to have sex because it'll hurt so bad
