Masturbation is all about having an orgasm without the help of someone else.

In the Asian Cowgirl position, the woman is squatting, which means that most of her weight will be supported by the feet. She can use her hands to take some of her weight by putting them on either the man’s chest or on either side of him on the bed.

Here is one configuration of the missionary position. The woman can lie on her back with her hips on the edge of a platform such as a bed, table, or desk while the man penetrates her while standing. The woman can move her body freely, she can rest her legs on the man or he can hold them or separate them.

There are different configurations of blowjob (or fellatio) and here is the example of 'whisper', also called 'recline & dine'. It is one of the most comfortable for the giver and the receiver.

In the ancient world, sundials were used to measure time but it would work only with sunlight, and they could not maintain a constant division of time. To compensate for these shortcomings, the water clock was invented. The oldest known example is dated to 1500 BC, and is from the tomb of the Egyptian pharaoh Amenhotep I. Here is a an example found in the tomb of Ramesses VI. The presence of a pharaoh with an erect penis is not explained, but the phallus is always a symbol of power, nothing to be ashamed of ^^
