Hi all, I've read about pre-cum, I never get any, but after I ejaculate - a while later I get a clear liquid flowing out of my penis. I clear out most of the cum the first time, but this only happens about a minute after I clean up. How do I get this to happen 'pre' instead of 'post' It messes me up after I'm done cleaning up and leaves stains on my undies. Help!!
