There are many problems that are uncomfortable to discuss, as a result, they are often avoided. Jesus did not back-down from embarrassing topics. Jesus opened the commandments, examined the hearts of men (and women) and gave advice and instructions to achieve a good life. It is not possible to find a way to "sin and get-by". There are always consequences for our actions and behaviors.

Chapter 19: The Sermon on the Mount
...You have heard that it was said to them of old time, You will not commit adultery: But I say unto you, that whoever looks on a woman to lust after her has committed adultery with her already in his heart.
And if your right eye offend you, pluck it out, and cast it from you: for it is profitable for you that one of your members should perish, and not that your whole body should be cast into hell. And if your right hand offend you, cut it off, and cast it from you: for it is profitable for you that one of your members should perish, and not that your whole body should be cast into hell.
It has been said, Whoever will put away his wife, let him give her a writing of divorce: But I say unto you that whoever will put away his wife, saving for the cause of fornication, causes her to commit adultery: and whoever will marry her that is divorced commits adultery.
Again, you have heard that it was said to them of old time, You will not perjure yourself, but will perform unto the Lord your oaths: But I say unto you, swear not at all; neither by heaven; for it is God's throne: Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King. Neither will you swear by your head, because you can not make one hair white or black. But let your communication be, Yea, yea; nay, nay: for whatsoever is more than these comes from evil.
You have heard that it has been said, An eye for an eye, and a tooth for a tooth: But I say unto you, That you repay not evil: but whoever will smite you on your right cheek, turn to him and offer the other also.
And if any man will sue you at the law, and take away your coat forbid him not, let him have your shirt also. And whoever will compel you to go a mile, go with him two miles.
Give to every man that asks of you, and from him that would borrow of you, turn not away. And of him that takes away your goods ask them not again.
You have heard that it has been said, You will love your neighbor, and hate your enemy. But I say unto you which hear, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That you may be the children of your Father who is in heaven: for he makes his sun to rise on the evil and on the good, and sends rain on the just and on the unjust.
For if you love them which love you, what reward have you, what thank have you? Do not even the publicans the same, for sinners also love those that love them? And if you salute your brethren only, if you do good to them which do good to you, what thank have you, what do you more than others? Do not even the publicans and sinners so? If you lend to them of whom you hope to receive, what thank have you? For sinners also lend to sinners, to receive as much again. But love your enemies, and do good, and lend, hoping for nothing again and your reward will be great, and you will be the children of the Highest: for he is kind unto the unthankful and to the evil.
Be therefore merciful, as your Father also is merciful. Be therefore perfect, even as your Father who is in heaven is perfect. Take heed that you do not your charity before men, to be seen of them: otherwise you have no reward of your Father which is in heaven. Therefore when you do your charity, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, They have their reward. But
