I am eager to know more about different religions from Islam to Judaism. Furthermore, how different religions look at women and comparing their kinds of approaches to the matter of gender and sexuality is one of my favorite topics of research. For the beginning I would like to know what is the idea of Judaism about out of marriage relationship between men and women. I do not mean prostitution and dealing intercourse and money! But having sexual relationship with opposite sex according to the personal choices out of marriage.

Please if you are going to use jargon in your answer, add the equal terms in English too. I am not familiar with Judaism's terminology but surely I would understand them if they would be in English. At least I can search them in the internet to understand.
