blinks Well…For number 2, sex is haram in any shape or form before the nikah nama is signed. I don’t kow where you came up with the idea of sex slaves but…not allowed. It existed way before Islam came into the picture. The idea of sex slaves was something that came from the kafrs. It also falls under rape since it in non-consensual.
Even I will admit that you are very wrong in this way of thinking. The first point does not come from Islam, but from the messed up ways of thinking of various cultures that distort anything and everything to suit their own needs. If you read through hadith and the qu’uran, and go to the islam-qa site(favorite site btw) a lot of stuff will be explained to you. The scholars there(the site) are very knowledgeable and fair.
