Jesus said, if you sin with your hand then you should cut it of than go in sin, and some other stuff he said, he also said that you can make a sin with your mind, but clearly we are not able to not commit a sin. That is why The Savior Jesus came to save us.
Every have made a sin and will do it. (Except Mr Jesus then)
Ask for forgiveness and you shall be forgiven, There is not our duty to judge who is living in sin or what is sin. Jesus says(john8:15) "You judge by human standards; I pass judgment on no one."
So, Ask for forgiveness if you are think that you committed a sin, Cuz it is not our duty to judge,
(now i'm not saying that you can skip what Jesus said, you value what Jesus said and think about it clearly. Jesus was wise, but never clear on the answer.)
