I want to have sex with a woman who is in a relationship
Are you attracted to the married woman?
I tend to lean that way towards a married woman.
You can't help who you are attracted to but you should avoid people who are in relationships. People will think that you are a homewrecker.
Who cares, people are not going to judge her or me. What's wrong with having a casual sex without commiting?
It's normal to have attraction towards different people regardless of the situation. But giving into those urges that you have for married women will not be beneficial to you. I recommend you just look for someone that is single.
