What is an Erection?
An erection is a physiological phenomenon in which the penis becomes harder, firmer and enlarged. This is usually caused by sexual arousal, although it doesn’t necessarily have to involve sexual pleasure. In an erection, the penis is caused to swell with blood, which causes the erection and increases sexual pleasure.
What Causes An Erection?
An erection can be caused by sexual arousal, physical stimulation, or even psychological triggers. Sexual arousal occurs when our bodies receive signals to become aroused, such as through touch, sight, sound, taste, or smell. Physical stimulation can involve touching, rubbing, or massaging the penis in order to create arousal. Psychological triggers can involve fantasies, memories, or other sources of arousal.
What Happens During an Erection?
When aroused, the penis swells with blood, leading to the penis becoming harder, bigger, and more sensitive. During an erection, the glans, the head of the penis, will become more sensitive and can be more pleasurable to touch. The entire penis may also become more sensitive, resulting in increased pleasure during sexual activity.
How Long Does an Erection Last?
The length of time an erection will last varies from person to person, but on average it can last anywhere from a few minutes to several hours. It is important to note, however, that if an erection lasts longer than 4 hours, it is considered a medical emergency, and should be dealt with immediately.
