My hypothesis: Science recognises only the outer-sex of people. Outer-sex refers to our sexual/ reproductive organs. So a person with a penis/ testicles is a male while that with a vagina/ uterous is a female. This definition is enough if we want to look at biology as only meant for reproduction. Science recognises only two outer-sexes, Male and Female but actually there is also a third one called Hermaphrodite. There is also an 'inner-sex' which science doesn't really acknowledge, but which all traditional societies are aware of --- some more than others. Our complete biological SEX identity consists of our outer-sex plus our inner-sex. Our inner sex can be described as our inner-sense of being a male or a female irrespective of our outer-sex. My hypothesis is that this 'inner-sex' is also determined by (hence unknown) biological factors. Inner-sex refers to our natural gender or our 'GENDER ORIENTATION''. There are three kinds of gender orientations: masculine, feminine and hermaphrodite (meterosexual). An ideal society would accomodate our outer-sex as well as our inner-sex into its Gender (and Sexual) identities. Actually an ideal society would not have any sexual identities. Is Gender Orientation natural/ biological? What do you think? P.S.: More about 'Gender Orientation' in males: a.) Natural gender or the 'sense' or 'feeling' of being male/masculine or female/feminine happens in degrees. On one extreme is an extremely masculine inner-sex, and on the other extreme feminine inner-sex (transexuals). Most people have both the genders in varying degrees. b.) It is our Gender identity which is our basic natural identity (not sexual oreintation). It is how we see ourselves, and how others see us. It determines how we relate to others and how others relate to us. E.g., a feminine gendered male may see himself as a basically a female, and relate to others as a female, inspite of a 'male' outer-sex. Others too would relate to him/ her as a different 'sex' than 'male' (again inspite of his/her outer-sex). In several respect one's inner-sex is more important to an individual (and to the society) than one's outer-sex. Although, its the unique combination of the two that determines our real SEX IDENTITY. c.) Our Gender orientation/ identity refers to our predominant Gender. E.g., a male who predominantly feels a male will be a masculine gendered man. It does not mean that the man will not have any feminine energies at all. d.) Our natural Gender or masculinity and femininity are not just social constructs (even though there is also a parallel 'Social Gender' that interferes with our 'natural gender'). They are real and are a product of biological factors. They represent our source of special energies. Masculine and Feminine Energies. Combined with our outer-sex the energies take different forms and invest the individual with unique powers. E.g. a predominantly feminine male will have the feminine energies of a female while the physical capabilities of a male. e.) SOCIAL GENDER: Apart from out natural gender, the society has created its own artificial, social gender --- which has a special significance in the case of men. Because 'Manhood' (Social Masculinity) is used as the basic manipulative tool to control the behaviour, attitudes and mores of men. However, this social gender is purely an artificial construct which may have nothing to do with one's natural gender and may in fact run contrary to the essence of natural gender. Some examples of social gender: Cigerrette smoking is projected by the society as a 'masculine' thing. However, in reality there is nothing masculine about smoking ciggerate. It's only when masculine men smoke ciggeratte that it seems masculine. Like social masculinity. social femininity is also equally artificial and sometimes 'false' and is used to control or punish men. E.g., Men may be told they are feminine when they cry do other things artificially desinated as 'feminine'.
