From “How to Make Love: A 1936 Guide to the Art of Wooing“, which offers:
The restrictions that bound us in the past, in the matter of social etiquette, have all been washed away by the cleansing waters of time. Not many years ago, our girls were warned to keep their young men from placing their arms around the seat of the buggy when riding or else suffer the ignominy of being classed as fallen women. Nowadays, we look upon such things more calmly. With the change in social customs there has been a need for a book which dealt with the art of love. This book is intended to aid you in your love-making.
Skipping to the good bits, Maria Popova summarises the following on Brainpickings.org, where in a section titled “How to Approach a Girl,” the author presents a guide to that coveted first kiss:
In kissing a girl whose experience with osculation is limited, it is a good thing to work up to the kissing of the lips. Only an arrant fool seizes hold of such a girl when they are comfortably seated on a sofa, and suddenly shoves his face into hers and smacks her lips. Naturally, the first thing he should do is to arrange it so that the girl is seated against the arm of the sofa while he is at her side. In this way, she cannot edge away from him when he becomes serous in his attentions. This done, on some pretext or other, such as a gallant attempt to adjust the cushions behind her (tenderness, you see) he manages to insinuate his arm, first around the back of the sofa and then, gradually, around her shoulders.
If you suspect this might be getting dangerously close to date-rape territory, hold the premature evaluation — we’re getting there:
If she flinches, don’t worry. If she flinches and makes an outcry, don’t worry. If she flinches, makes an outcry and tries to get up from the sofa, don’t worry. Hold her, gently but firmly, and allay her fears with kind, reassuring words. … However, if she flinches, makes an outcry, a loud stentorian outcry, mind you, and starts to scratch your face, then start to worry or start to get yourself out of a bad situation. Such girls are not to be trifled with … or kissed.
Provided no face-scratching has taken place, this is what you should do:
Tell her she is beautiful. Then take a deep sniff of the perfume in her hair and comment on it. Tell her that the odor is like “heady wine.” Tell her that her hair smells like a garden of roses. Tell her anything, but be sure to tell her something complimentary. This done, it is only a natural thing for you to desire to sink your nose deeper into her hair so that you can get the full benefit of its bouquet.
Then, time for “The Technique of Kissing”:
Now is your chance! The moment you feel the tip of your nose touch her scalp, purse your lips and kiss her, the while you inhale a deep breath of air that is redolent with the exquisite odor of her hair. It is then but a few inches to her ear. Touch the rim of her ear with your lips in a sort of brushing motion. Breathe gently into the delicate shell. Some women react passionately to this subtle act. Brush past her here in this way again and note her reaction. If she draws her head away, return to the hair and sniff luxuriously of it. Then settle back to her ear, the while you murmur “sweet, airy nothings” into it. From the ear to her neck is but another few inches. Let your lips traverse this distance quickly and then dart into the nape of the neck and, with your lips well pursed, nip the skin there, using the same gentleness as would a cat lifting her precious kittens.
Then, with a series of little nips, bring your lips around-from the nape of her neck to the curving, swerve of her jaw, close to the ear. Gently kiss the lobe of her ear. But be sure to return to the tender softness of her jaw. From then on, the way should be clear to you. Nuzzle your lips along the soft, downy expanse until you reach the corner of her lips. You will know when this happens, because, suddenly, you will feel a strange stiffening of her shoulders under your arm. The reason for this is that the lips constitute one of the main erogenous zones of the body.
All right. You have subtly kissed the corner of her mouth. Don’t hesitate. Push on further to more pleasurable spots. Ahead of you lies that which had been promised in your dreams, the tender, luscious lips of the girl you love. But don’t sit idly by and watch them quivering…
Propriety prevents me from indulging further, but if you read the original article, you’ll get the thrilling denouement all to yourself.
