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 & 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 & 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 & should rather acknowledge individuality even among the genders. It seems that the Buddha is over-generalizing, or did the miss the boat?
