You might want to think twice before dialing that next booty call.
Carried out by researchers at the University of Texas at Austin, the study aimed to look beyond the purely physical factors typically examined in studies on sexual pleasure, such as length of time spent engaged in sexual intercourse and number of orgasms achieved.
"What we wanted to do was just really to cast a wide net and see which (reasons) were associated with people being satisfied with their sex lives," researcher Kyle Stephenson told LiveScience.com.
Their findings revealed that of the men surveyed, most felt less satisfaction when having sex to raise their self-esteem or to gain some material good or resource.
The researchers also determined that, for women, satisfaction is less associated with love or commitment than it is for men. Rather, women are more satisfied when having sex to communicate gratitude or apology to their partner, which is probably why make-up sex is always significantly more awesome than regular sex, and why anniversary sex is usually just kind of okay.
