women love adventure as much as men.. or even more... Besides... there are no good boys or bad boys. and if you want to consider that.. well.. in that case my answer would be:
Because bad boys are more fun! xD
Besides,, hanging out with a man.. doesn't necessarily mean you have to have sex with them or whatever.
And truth be told.. most women I know have been with a bay boy at some point in their lives.. and all say the same
" been there,, done it.. over"... but all of them admit.. it was fun!
