When i see a porn or i touch a girl for sex there is something lubricant comes out from my penis even before do the sex its natural or not ?

Cowper's Glands: The clear fluid a male secretes prior to sex or when aroused is a preejaculatory fluid from the cowper's glads in the body. It readies the penis for the sexual encounter and is normal. If you have other symptoms or what you experience is not the above, please see your doctor, who will be able to give you further information. Peace and good health.
