When my penis is erect, if I touch my glans, my penis hurts a lot. What could be the cause of that?

Hello, Vardhan0011.

Some potential causes of pain when touching the glans during an erection include:

Balanitis: Balanitis is the inflammation of the glans penis. It can be caused by infection, poor hygiene, or irritation. Infections, such as yeast infections or bacterial infections, can lead to discomfort and pain.
Phimosis: Phimosis is a condition in which the foreskin of the penis cannot be pulled back over the glans, leading to irritation and pain when the glans is exposed.
Injury or Trauma: Any recent injury or trauma to the genital area, including rough handling during sexual activity, can cause pain when touching the glans.
Allergic Reaction: Some individuals may be sensitive or allergic to certain lubricants, soaps, or other products used during sexual activity, which can lead to irritation and discomfort.
Sexually Transmitted Infections (STIs): Certain STIs, such as herpes or syphilis, can cause genital discomfort and pain. It's important to get tested for STIs if you're sexually active.
Priapism: Priapism is a rare but serious condition in which an erection lasts for an extended period and can cause severe pain. It requires immediate medical attention.
Psychological Factors: Anxiety, stress, or other psychological factors can sometimes lead to physical symptoms, including pain or discomfort during sexual activity.
