Sex and violence, no, but romance and colorful characters - by all means. Okay, assuming the lead has not run out on your pencil, you'll want to come up with a compelling ending, something to leave people laughing or weeping or thinking. "The tattooed lady and the dwarf lived happily ever after" has been done before and is a cop-out anyway, but on the other hand you don't want to be TOO colorful and end up jarring the reader's sensibilities with something like "Griselda the Fat Lady, who had loved the dwarf in secret for years, covered Lavinia's mouth with one enormous paw as she slept." hot sex story
How about: "Lavinia carefully placed the orange and her paramour, Sergei, in the trunk, and, summoning the porter, she left the hotel." This is an ending suitably conclusive yet tinged with mystery. To sum up, story length, subject matter, and an ending are three of the most important elements to keep in mind when writing a short story. There's another element, however, more important than all the others. I'd tell you what it is, but my pencil point's about to run out.
Premature ejaculation is something that can tear at you week after week, affecting not only the relationship with your lover, but most likely preventing you from getting involved in a new relationship or even a one night stand. Some individuals have given up on sexual pleasures altogether because of a premature ejaculation problem. When things reach this level it's time to put your game face on, become committed, and stop premature ejaculation. My own personal experience with premature ejaculation was horrendous. I experienced both of the above, prevention from getting involved in a relationship, and finally when a relationship did happen by chance, many months went by without having sex due to my inability and lack of confidence to stop premature ejaculation.
