Is it sinful for a female to kiss a male even if it feels good, satisfying and would be considered by me as a sign of affection and not sex?
His Grace Bishop Youssef:
If kissing did not feel good no one would have the desire to do it. Like everything else in life there is a time and a season for everything. Kissing a guy who is not your husband is definitely wrong no matter how good it felt. Since you felt good this implies that you would not mind doing it again! And when you do it again, this ‘affection’ will not stop at kissing but you will desire more intimacy and as St. James says, “But each one is tempted when he is drawn away by his own desires and enticed. Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death” (James 1:14).
When you kiss you are allowing a guy to have privilege over your body. This privilege should be given only to your husband and no one else. The Holy Bible says, “Do you not know that you are the temple of God and that the Spirit of God dwells in you? If anyone defiles the temple of God, God will destroy him. For the temple of God is holy, which temple you are” (1 Cor 3:16-17). God wants us to seek guidance form scriptural truth not feelings. Affection or love looks beyond personal desires and the momentary gratification of the senses. It looks at the big picture: serving others and glorifying God. Do not think of what you want, but at what God wants.
