Sex is a normal part of adult life and can have both physical and emotional effects. Many online claims exaggerate or spread misinformation, but medical experts agree on the following proven facts:

1. Physical Effects
Sex can cause temporary physical changes such as increased heart rate, muscle relaxation, and hormone release. It may also improve blood circulation and help reduce stress. In healthy individuals, these effects are normal and not harmful.

2. Emotional and Hormonal Impact
During sex, the body releases hormones like oxytocin and endorphins. These are linked to feelings of bonding, relaxation, and emotional connection. This is why many people feel closer to their partner afterward.

3. Risk of Pregnancy
If protection is not used, pregnancy is possible. This is a natural biological function, and contraception can help prevent unintended pregnancy.

4. Risk of Sexually Transmitted Infections (STIs)
Unprotected sex can transmit infections such as chlamydia, gonorrhea, or HIV. Using protection, such as condoms, greatly reduces this risk.

5. No Permanent Damage in Healthy Situations
Sex does not permanently damage the body when it is consensual and safe. The reproductive organs are designed to function normally during sexual activity.

6. Mental Well-Being
For many people, sex can improve mood and reduce stress. However, emotional effects depend on personal circumstances, trust, and relationship quality.

Important: Safe sex, mutual consent, and proper protection are key to protecting both physical and emotional health. If someone experiences pain, unusual symptoms, or concerns, they should consult a healthcare professional.
