I think it is one of Jorges Gang movies, i don't know which one tho. Hope it helps!

If you really know the wife you shouldn't do it.

There isn't a rule. If the person is right, you should feel free to talk about sex right from the start. Having sex on the 1st, 2nd or 3rd date doesn't change the prospect of the relationship.

Yes. A relationship is not only about sex. Even if it is only a sexual relationship you can do so much without actual penetration, and you can always add a 3 person.
