I'm going to have relations with a woman who is taken
Do you know who her husband is?
It's part of my learning process. I intend to find out soon.
Relationships with people who are taken are exciting to you, but in this scenario you should leave well enough alone. If you go out with her then things might get ugly. What if he kills you over it?
It's worth being murdered for sex. Do you think I will get arrested?
No, you will not be arrested, but having sex with a married woman is wrong and is a terrible thing to do. How would you personally feel if you had a wife and she was unfaithful towards you? It does nothing for either person and will hurt you.
