Kisses, touches, hugs, caresses etc. (can be sinful or non-sinful). All kisses, touches, hugs, and caresses performed for the sake of lust or sensual pleasure is mortally sinful and must always be avoided at all cost by all people at all times. Natural touches, kisses, hugs, caresses, embraces and the like (such as those performed by family members and by lovers in public) are not sinful provided they are not performed for the sake of sensual or lustful reasons. Spouses must be aware though, for even though it is not sinful to embrace one another out of affection, excess or unreasonability in embracing happens easily during the heat of concupiscence, and this is certainly sinful. Also, if spouses hug or kiss each other out of affection and they perceive that their lust is aroused by this act, they must immediately cease with this deed that is arousing their lust or be guilty of the mortal sin of unlawfully inflaming their lust. The more spouses indulge in these lawful embraces and are careless therein, the more likely it will become sinful. So to be on the safe side and to become perfect, spouses should never touch, kiss or even see each other naked during intercourse. Kissing and touching before intercourse are also particularly problematic as they lead to intercourse that is not governed by a desire to procreate. Spouses should also never walk around at home undressed or partially dressed. Women especially should never walk in their underwear or naked in the presence of their husband, as this behavior without a doubt will incite his lust. This specific problem we have today of people walking around naked or dressed like whores in public or at home was typically unheard of before in society, as most men and women in the past was much more well dressed and modest, even at home. As an example demonstrating this fact, consider how women’s underwear looked like just 200 years ago. Believe it or not, but these underwear were in fact more modest than what many women wear as skirt or dress in public today!
