People who don't agree can just answer this simple question : Why does a married woman only needs a guy for emotional support? Can't she have a good friend of the same sex who can provide whatever support she requires?

Looking for some comments on the topic. Let me clarify the topic again :

It is not difficult to find a married man / woman in an extra-marital affair who states that he / she has entered this affair for the sake of emotional support only. He / She is not interested in Sex! Is he / she speaking the truth or is he / she lying?

I believe that he / she is lying. But i may be wrong. People who believe that he / she is not lying, please answer this simple question. Why can't this person look for a friend of the same sex ? Can't a man get emotional support from another man ? Can't a woman get emotional support from another woman?
