the last one because she'd probably save me if I get attacked by wild animals.

why do you have 6 options when you have only 5 pictures 

I think I would choose the 6th one. The other 5 looks like theyre 12 years old.

I'd prefer to date women, a lot more fun and a looooot less trouble.

The first 5 are probably traps or were male at one point in their life. Choice 6 looks like a real one I hope.

None of them, they look like 12 years-old 

Honestly none of them. Guess we know what kind of girls OP likes :)

Well, I know nothing of their personalities just by looking at the pics, but maybe this is a test to see if people would make a decision based merely on looks.

3 or 5. The last one looks strung out.

Out of those choices? None. #6 if you put a gun to my head.

It should be which one of these 'girls' gives you nightmares.

Like someone else said above, choice #6 would probably protect you through a dangerous dark forest and speak the tongue of the wolves.
