Buddha's view on sexuality In contemporary society (apart from religion) sex is mostly seen as something pleasurable, which is done even without considering childbearing.

As far as I can see, Buddha taught extensively to lay people how to treat each other friendly &amp; compassionately, but omitted the bodily intimacy aspect of it.

It's largely sensual desire that binds human couples together, and I am not merely referring to appearance, but also the craving to be touched etc. (as it's always correctly pointed out in the suttas: Pleasant feelings at the 5 sense doors)

Q1: Did the Buddha remain silent on these matters because of a specific reason?

Q1.1Was the Buddha even concerned about sexual objectification &amp; did he suggested perhaps sexual repression?

Dhammapda 242 states:


  Unchastity is the taint in a woman


Q2: Could it be that a majority of Buddha's teaching are timeless, but few are open for change, due to different societal context etc.? (e.g., 3rd precept)

Q3: In the above quote, isn't it a bit biased to state that it's ONLY a woman's taint? Why not a man? Why focus overly on women?
Back in those days, there were probably fixed gender roles, but I believe society should progress &amp; should rather acknowledge individuality even among the genders. It seems that the Buddha is over-generalizing, or did the miss the boat?
There are two levels of Teaching, for the common people, and for professional seekers of Nirvana. 

To first, Buddha taught no-nonsense ethics, chastity etc. Sex for procreation, faithful marriage, these kinds of things. Going mostly by his basic principle of "what leads to peace and harmony is good, what creates causes for potential conflict is bad" - applied to the social norms of those days. 

To the second, he taught universal principles operating at cosmic scale. Natural evolution ("dependent origination") emerges as cyclic self-perpetuating tendencies. These self-perpetuating tendencies culminate in arising of sentient experience. Information trapped in these tendencies identifies some elements of this experience as "self". What in reality is a perpetuating part of the tendency (its capacity for continued existence) in sentient experience arises as something subjectively desirable. This includes sexual attraction.

Therefore, breaking through the charm of seemingly pleasant, and correctly attributing its nature to the self-perpetuating tendency for continued existence, is an appropriate component of practice leading to liberation from the trap of subjective experience.
