Lets think reality here when it comes down to it were animals. Sex is part of life and its an uncontrollable feeling to get horny. If god didn't want us to have sex for procreation then we wouldn't hit puberty till we were 20 or so. In nature if we hit puberty and are capable to procreate at 12-14 then it was intended for us to have sex at those ages. this is in a natural animalistic type of world i am intending this for. girls having tits are sexual cues relating to the fact of having sex and to know that they are ready to bare children. I am not the religous type and i feel if your responsable about it then by all means enjoy it. I like to look at things how god intended. naturaly and in reality. tribes start marriage and sex at very early ages its natrual.
