If you are cramping up it means you are not adequately stretching and warming up all those love muscles prior to the main event. I suggest as a warm-up you extend your foreplay for an additional fifteen minutes at least by increasing the stretching, tugging, hip gyrations, handstands, pushups and squats . Remember, to be effective you cannot count on just static stretching, you must include series of dynamic and active movements that start with low impact, low intensity and progress naturally to high intensity, full speed activity that simulates the action and intensity of the upcoming event. That way you can get the blood flowing into the right muscles through a natural progression.
Think about it: how often does a person hold a stretch position as part of their active lovemaking? That is right, not very often. So if you are still using this method to get ready to go, you are not getting the most out of your ability.
Remember, good foreplay should take at least 20 to 25 minutes to complete. This will reduce the likelihood of injury by ensuring that you do not try to go too fast too soon. In addition, you will get the most out of your muscle because you followed a thought-out progression of movements that went from low intensity tugging and stretching to high intensity speed development drills and exercises.
By the time you have finished your foreplay, you should be lightly sweating, fired up and ready!
Another issue to note when doing engaged in any kind of sexual activity is to make sure that you are performing correctly. You compete like you practice. If you are not performing and drilling correctly you are going increase the likelihood of injury by adding unnecessary stress.
Sexual positions are designed to be done a certain way for a specific reason. If you are not technically sound during the warm-up you will not be technically sound in bed where and when it counts. Foreplay is the foundation of the evening’s activities and sets the tempo for all that is to follow it.
And don’t forget the need for proper hydration both before, during and after sex. Dehydration can be a major factor in muscle cramps and strains. Consider increasing your bodily fluid intake to the maximum you can handle! Output is determined by input!
