I have had a huge amount of precum ever since high school. Tons of it. I have always enjoyed it, not only for lubrication, but just to watch it ooze out and knowing shortly I will shoot my cum load. My wife likes it, up to a point. When we first started having sex she complained about the wet sheets. So what we did was she would just slip a condom on me while we have sex play. When I am ready to enter her, off comes the condom. That way the sheets are dry, I still have lots of precum, and then I can get my cum load off.
