Why do some guys ejactulate so quickly?

Some guys ejaculate quickly due to factors like heightened arousal, anxiety, or lack of sexual experience, which can lead to less control over their orgasm. Psychological factors, such as stress or performance pressure, can also play a significant role. Additionally, biological factors such as hormonal levels and sensitivity can contribute to quicker ejaculation. It's important to note that this is a common issue and can often be addressed through communication, techniques, or professional guidance.
