Just masturbate regularly! 'Cause if you don't, you will eventually have a messy wet dream to clean up! Also, imagine having sex with "that special someone" for the first time, and ejaculating like this! She might think you have a disease or something (of course you don't, but it'll look... wrong and it may turn her off to you... indefinitely). Well there's my advice on a scenario gone seriously wrong! I like exclamation marks!!!!
