"Sexual intercourse and the sexual relationship with a legal spouse are governed by nature, and at the same time is a sunnah of the Prophets and the Ahlul Bayt (as). It has even been referred to as the most pleasurable thing in life. A group of companions and Shī‘as of Imām as-Sādiq (as) narrate that the Imām asked us: “What is the most pleasurable thing?” We said: “There are many pleasurable things.” Imām said: “The most pleasurable thing is making love with (your) spouses.”" Sexual Etiquette in Islam in "From Marriage to Parenthood: The Heavenly Path" by Abbas and Shaheen Merali
Unearned reward? No. Thanks. It's demotivational.
Motivation being rooted in a basic need to minimize physical pain and maximize pleasure, can be easily devastated by factors which undermine, weaken, or break the link between effort and reward.
Providing with something valuable for nothing, or giving an unearned reward to those who do not deserve it, is demotivational. Without motivation people are not capable to achieve goals. Motivation is the willingness to expend a certain amount of effort to achieve a particular goal. (Biehler, R. & Snowman, J. (1990) Psychology Applied to Teaching, 6th edn. Boston: Houghton Mifflin)
