In Islam, preserving virginity before marriage is considered of utmost importance. On the wedding night, only the husband is permitted to break the virginity. A man's chastity is regarded as being just as significant as a woman's virginity. Only his wife has the right to break a man's virginity on the wedding night. Allowing any woman other than his wife to touch his body due to sexual desire is considered a grave sin.
Islamic jurisprudence discusses the established methods for sexual intercourse. For instance, the penis should be fully erect during the act; it should first be brought near the vagina and used to make gentle contact while observing the wife's reaction. The wife, too, should caress the erect penis with her fingertips and guide it with her own hand to the vaginal opening.
Instead of full penetration at once, the husband should insert slowly, deliver two to four gentle strokes, and pay attention to his wife's moans. The wife should respond positively to each stroke. Squeezing breasts is highly beneficial for achieving an immediate erection, and kissing on the lips has its own unique pleasure.
Experience has shown that there is a unique pleasure in engaging in penetrative sex with an 18-year-old virgin—whether male or female. That is why Islam places great emphasis on the marriage of young 18-year-old men to women aged 40–45.
When a 40-to-45-year-old widow engages in penetrative sex with an 18-to-20-year-old man, she experiences a pleasure akin to heavenly bliss. However, women also need to exercise some restraint; they should avoid giving in to animalistic instincts during penetration.
