Conditions Necessary for Sexual Arousal

Healthy sexual arousal is facilitated by many factors, some of them being:

1. Having a while since last engaging in sexual activities and having recovered his/her sexual fluid to some extent,

2. The body is energy-rich; food is consumed on time and there is no strong hunger,

3. Being free from diseases and disorders that affect amorous activities,

4. Having sufficient sleep, and

5. Some form of romantic and/or sexual attraction.

This is summarized in the infographic below:

If a person meets some of the above arousal criteria, then even a bikini pic is enough for arousal. But if not, then even actual pornographic content may not be sufficient for sexual excitation.

Another factor is the frequency with which people satisfy their sexual urges. A person in the habit of going 4 days without arousal will be easily aroused by their body every 4 days.

In the cold months the body assimilates food faster and is in a mode for mating, so arousal is extra facilitated in that time; along with meeting the above criteria.
