There are a myriad of solid reasons NOT to enjoy sexual pleasure on 9/11, such as safety, respect and religious zeal. Even more importantly, everyone knows that those who engage in sexual activity on 9/11 do not care about all the innocent people who died on 9/11. It was the day that everything changed. When those towers came down, American flags came out. Even so, one must completely refrain from masturbation, intercourse, and all forms of sexual stimulation on 9/11 in order to observe the holiday righteously.
