Erectile dysfunction and the psychology

Today there is a considerable number of men who are suffering from erectile dysfunction in any society. The main factor of causing erectile dysfunction is not physical weakness. Psychological stress is basically causing this. Confused psychological status is the biggest reason behind it

                        There is a number of factors which are causing psychological stress and a complicated situation. First one is living environment of people is too much of artificial. An artificial environment which contains a less amount of natural property can build up an extra psychological stress. Second one is the social condition without gender specifications. Gender specifications are naturally generating a sexual attraction between two sexes and it keeps a healthy sex drive. Naturally both men and women like to identify their opposite sex with unique specifications. A social environment with more gender based specifications is very pleasant and not generating psychological stress. That is how when gender specifications become less, it is generating stress. Generally men like feminine women with feminine gender specifications in any society. Because of femininity of women is naturally corresponding to men’s masculinity. On the other hand non feminine women are sexually unpleasant and generating a huge pressure on men’s psyche. This is how women’s behavior affects on men’s sexuality. These sexually unpleasant things are directly causing men’s sexual dysfunction. The third fact is complicated social situation. Today in any country, the lifestyles are complicated. And the majority of populations are selfish. This kind of a situation is a major fact which is generating psychological stress. Because of there isn’t much of co-operation in the society and people have to struggle for maintaining their lifestyles. Today people have to face problems alone and struggle individually. Finally all of these things are causing to collapse the psychological fitness of men for being active sexually. No meaning of taking medicine without getting rid of the whole background of generating psychological stress. Until we are being honest and accept the true nature of sexuality we cannot get rid of this bad situation. This can be difficult to achieve, because of gender hypocrisy has already driven the society in a crazy manner. And it does not allow people to accept the real nature of sexuality.

Evolution and the sexuality

The purpose of sexuality is reproduction. There are non sexual reproduction methods can be identified among simple beings and as well as within the world of plants.

However when the evolution of beings becomes advanced, Sexual reproduction method has promoted well and it became the dominate feature. As a result of transforming beings towards a progressive path, the world of creatures appeared. The world of creatures is superior to the world of plants. Dominate feature of the sexuality of plants is hermaphroditism. But within the world of creatures, unisexual creatures are the dominate group.  And the reproduction method also limited only to sexual reproduction within the world of creatures.

                        In the primary stages of evolution, the method of reproduction is simplex even though it is sexual reproduction. Male and female sex differentiation was also simple and that was only for generate the gametes. Most of simple beings were aquatic. Fertilization between simple male and female gametes occurred. When the creatures become evolutionally advance, the sexuality become advance too. The reproductive organs and tissue became complex. Growing the embryo inside a womb is the most advanced feature of reproduction. External genitals which can be well recognized were appeared. External genitals and the internal reproductive organs are pre determining by the sex chromosomes, so the genetic sex determination has taken the priority. Biochemical functions such as actions of sex hormones are also important in sex determination.

             One group of sex, either male or female is dominating the whole species of creatures. The capability of interact with the natural environment more actively is the fact of determining that. Dominating of male creatures is the most recognized feature. Female domination is rare and it is not evolutionally advanced. Mammals are the most advanced creatures in evolution. At last human beings are evolutionally superior to all other creatures. Human sexuality is more advance and it is complex too. Most outstanding feature of human sexuality is the psychological factor and this is known as gender. Physical and genetic factors of sex are common for both human beings and other creatures. If we considered about the hominid evolution, there can be identified a special path of psychological transformation. Human beings created cultural environments and civilized due to this reason. In any culture, gender specifications are conspicuous. Human beings are wearing clothes and this feature is unique to human beings. In any culture there are specific male clothes and specific female clothes. Gender specific human activities can be identified within any culture and they are common. Finally all of these specifications are for better attraction between two sexes. Matching up male sex drive and the female sex drive is an important and essential part of any civilization. Advanced gender specifications are advanced in evolution too.
