Are there any scientific papers that talk about the effects of intercourse on girls before puberty? I would like the consider that there's no force here. Just plain intercourse.

Most papers confirm that it’s impossible for a valid consent to come from someone so young and that the men who choose to proceed anyway are often mentally disturbed and poorly socialized.  

There’s also the issue if physical harm, tearing internally, and trauma that lasts for the lifetime of the female.

Well, but I'm considering that there's a girl here that hasn't reached puberty, and very little physical force was applied. Can she be hurt on the physical side?

Yes. You need to leave her alone and let her grow up.

Leave whom? I'm simply asking a question for a reason that you actually don't know. I'm not of course looking for a justification to go have intercourse with a child. I won't even have before marriage.

Marriage is irrelevant to this question, regardless of what silly religion you follow. 

The ability to validly consent is all that matters. 

Children cannot. 

This is doubly certain when they haven’t even reached puberty yet. 

Your god would not approve of harming a child. Such acts are harmful to the child. End program. 

Especially when so many “marriages” are shams specifically sanctioned by dirty religious leaders so sleazy slime balls can feel justified in forcing themselves inside a young girl.

This is not a medical topic and inches towards rather unsavory subjects. I am going to shut it down pending review by other modes.
