Is it normal to want somebody to seriously hurt me?

If you really wanna get hurt go pick a fight with a Samoan!
;-)

I can never understand why some people wish bad things upon themselves.

BOTH! Normal to 'want' and 'think', fantasize, write about, all that. But the avoidance of pain is hardwired and if you want it, you might be sublimating and want something INTENSE and "rushy". Creeps that are willing to help you with this might fuck you up long time.

No,it's not normal,I myself have felt this way at times in my life

Well, if you really want it... *smacks yo-- gurt packs* I'll be eating this, and I don't want to hurt you at all... You thought I was going to "cyberhit" you? Nonsense.

But, it sounds like you have the almost perfect life. Just that one dust particle, and it'll be clean! ...The dust particle is your wish to get hurt...

Interesting. I'm not sure if it's normal but I can sort of understand. From what I've heard of people who are into those sort of things it's all about losing control. Honestly I don't really have much advice on whether this is normal or not. I feel like all I can say is be careful what you wish for.

Sounds like you have a past history of abuse and neglect to me.
