Sex can be wonderful, but it can also be tricky. The science of sex is a broad field of research that encompasses many aspects of human sexuality, from physiology to the psychological and social factors that influence sexual behaviour. Over the years, researchers have been able to shed light on a variety of ways we can enhance sexual experiences in or outside of the bedroom. Arousal and desire play a crucial role in human sexuality. Arousal or excitement is a necessary component of sexual activity and can be triggered by a range of stimuli, including physical touch, visual cues, and psychological factors.
In the context of sex, desire or libido refers to the drive or motivation to engage in sexual activity. Arousal and desire are complex phenomena and can both be influenced by a variety of factors, including biological, psychological and environmental factors.
The sexual response cycle devised by William Masters and Virginia Johnson, who were known in the s for their controversial research into the physiology of human sexuality, refers to stages of emotional and physical changes as a person becomes aroused during sexually stimulating activities including intercourse and masturbation.
