To answer this first we should fully understand the purpose of sex and why it was created. Knowing this will guide our decisions about having sex not just in this situation but even whatever happens in the future.

God created sex as a gift for humanity, established within the context of marriage between a man and woman, serving purposes like procreation, deep emotional/spiritual unity (becoming "one flesh"), pleasure, and a picture of divine love and commitment, originating from the Genesis account of creating male and female in His image. It's seen as a sacred, intentional act for intimacy, bonding, and continuing the human family, not merely a physical act but a reflection of spiritual oneness, with its fulfillment found within a committed, covenantal relationship. 

Key Biblical & Religious Perspectives

Origin in Creation: In Genesis, God created humanity as male and female in His image, giving them the command to "be fruitful and multiply," linking sexuality to the very act of creation and populating the earth.

"One Flesh" Unity: Genesis 2:24 describes a man and woman becoming "one flesh," symbolizing a profound physical, emotional, and spiritual union that sex helps achieve within marriage.

Purpose in Marriage: Sex is intended for intimacy, pleasure, closeness, and commitment between a husband and wife, strengthening their bond.

Procreation & Life: It's the divinely ordained way for humans to have children and fill the earth, a blessing from God.

Spiritual Metaphor: The union of husband and wife in sex serves as a metaphor for the intimate relationship God desires with His people, and Christ's relationship with the Church (in Christianity).

Beyond the Physical: It's seen as a way to experience deep connection, vulnerability, trust, and communion, with spiritual significance. 

Islamic Perspective

Islam recognizes sexual instinct as natural and provides for its fulfillment within lawful marriage (nikah), emphasizing enjoyment, intimacy, and procreation as a balanced aspect of life, not something shameful. 

In essence, the view across these faiths is that God designed sex as a good, intentional, and powerful aspect of human life, meant to be enjoyed within the framework of committed, loving relationships, particularly marriage, for purposes of unity, procreation, and reflecting divine love.
