Ok, so just follow me here for a minute or two and just think about it!

So, let's say you have a boyfriend or a girlfriend. So you do your daily stuff together, watch movies, clean the bedroom, go shopping etc.
Or both of you head to work and come back home during the evening.

Take showers hop into the bed, start watching something on TV or pop in a movie.

Then either you or your partner start to have these animalistic instincts. Or both of you at the same time..who cares.

Then from a basic sensation of touching each other organs and body parts, your hormones begin to work and there is this chemical reaction takes place in your body and also in your brain. You continue to incite others by using various technics, involving your fingers, your tongue and your lips and both of your entire bodies become nothing but a giant sex organ that reacts to these stimulations of wanting more.

Just from this part of sticking your male organ into the female organ you do this for a certain amount of time, let's say 1hour 25 minutes, for which you delay a certain reaction to take place which cause something we call a climax..and at the end of a successful operation from both sides, you and your partner lies there exhausted.

Now it's time to sleep and "somehow" you feel satisfied and your problems seem to be gone for a few minutes and the only thing counted for you was to execute this certain instinct produced behavior and cause "pleasure" to your partner while making sure you enjoy it too.

Once your hormone levels and testosterone levels return to normal and you recover this whole experience just becomes a memory. If you are good enough like certain people, you can also repeat this entire activity about 20-30 minutes later, and perhaps you can keep repeating this until you are physically exhausted. Some people are very doing this stuff, thanks to their physical strength, stamina and treshold and sexual drive.

But at the end you are exhausted and you will eventually fall asleep. Having doing this sort of an activity multiply times a week can lead to sleep deprivation and poor peformance at your job and the usual signs are well visible on people - careless look at early mornings and sleepiness at early afternoons.

You might be also suffering from the "penguin walk" if you are a female, while the guys might complain about their knees suffering 1rd degree burns, their tongue might feel a bit ackward for stretching it too much, other times muscle pain at the stomach and the waist for doing certain motions for an extended period of time at the previous night and the previous days.

And you have to deal with all these problems, just because you traded your available sleeping hours to an activity which only lasted only a few hours from the rest of the 24 of the day.

I love short girls! So maybe 4'6" is too short lol...to go down that dark road a bit, if standing up her face is at you belly button that's either too short or too tall!
