Hi I m 22 year my question is this when I watch porn movies a fluid is comes out it's not sperm u said it's normal ohk but after watching long time porn videos like for 4 to 5 hours I have a pain in terus until I hand practice
You are VERY normal.
The fluid you see is precum, because your body is aroused sexually. It's getting ready for sex.
Your testicles hurt because of the same reason. It's called vasocongestion. There is more blood flow to the genitals during arousal.
You have what is commonly called "blue balls." You can masturbate to relieve the discomfort. It should go away after a few hours regardless.
Hope it helps.
