Doctor's answer:

Common sexual positions include the following four:
(1) Male-on-top (natural position): This position is favored by most women, as the front-facing breasts and mons pubis experience greater pressure, producing tactile pleasure from skin-to-skin contact and the euphoria of intimacy. The disadvantage of the male-on-top position is that the woman has limited mobility and fewer opportunities for direct clitoral stimulation.
(2) Female-on-top: This position widens the vaginal opening, allowing even men with smaller penises to provide strong stimulation for their partners. It can help premature ejaculation patients control ejaculation, as well as men with erection difficulties alleviate anxiety and discomfort, thereby improving erections.
(3) Side position: The side position allows both partners to avoid bearing weight, so even if the session lasts longer, neither will feel tired. It facilitates free movement and flexible pacing. The side position also helps men control ejaculation and manually stimulate the woman’s nipples and clitoris, which is particularly suitable for men with longer penises.
(4) Rear entry (also known as the missionary position): The woman adopts a knee-chest position, supported by her knees, chest, and elbows on the bed, while the man kneels behind her, supporting her hips with his hands and inserting his penis. The rear entry position offers variety and more (romantic), and in most cases, it facilitates manual stimulation of the breasts, nipples, and clitoris, helping the woman reach orgasm more quickly.
