Ask Sexpert: What is Nightfall?

Q: I am 24 years old. For the past eight years, I have been experiencing nightfall two to three times a week. I stopped masturbating long back. Due to nightfall, I have become very weak. Whenever I get sexually excited, a white sticky fluid is secreted from my penis. Please help.

A: Nightfall is a natural experience. If you masturbate, nightfall will stop. Both are harmless. What you see on getting excited is a lubricating fluid secreted by a special gland meant to do just that. So stop worrying.
