Sexual arousal is the feeling animals and humans get when they are ready to have sexual intercourse.

Sexual arousal in people[change | edit source]

When people become sexually aroused, their bodies change in certain ways.

In women: In men:
Female sexual arousal. The nipples are erect. Inside her body, the uterus may have moved backwards while her vagina starts to expand.
Male sexual arousal. The penis has started to swell up, the veins are starting to show, and the foreskin has begun to slip back. The testicles have tightened in the scrotum. As the penis continues to swell it will point upwards.
  • The penis will swell up and become stiff (erect) so it points outwards and upwards. This is the clearest sign of sexual arousal in men.
  • The veins in the penis will stand out.
  • pre-ejaculatory fluid will leak from the end of the penis to help lubricate it.
  • The foreskin will slip back, exposing the glans penis.
  • The testicles will swell and be pulled upwards.
  • The scrotum will thicken as the testicles tighten.

Animals[change | edit source]

Animal sexuality is not very well understood today, but scientists are sure that animals do get sexually aroused without having sexual intercourse. Dolphins and Bonobos both use sex as a "social tool to strengthen and maintain bonds."[2]
