I have a couple of questions regarding the Viewpoints of sexuality in Buddhism for lay people.
Why is lust seen as being unskillful? Lay-people are lay-people because they don't want to renounce worldy life; they strive for 'heavenly realms' instead of nibbana. What's unskillful in a natural urge? Non-engagement won't decrease the urge either.
In a sutta the Buddha said the consequences of an action are important, and this is the reason why he abandoned thoughts of sensuality, because it harms others and himself. It obstructs wisdom (this is true because it hinders Nibbana), but why are sensual/sexual thoughts dangerous? If I lust after a woman in a healthy, non pathological way, I see no danger there. As long as I don't sexually harass her? Maybe she has sexual fantasies as well?
Samadhi is 'achieved' by the momentarily stilling of the 5 hindrances. Elsewhere it was stated that past sankharas influence present sankharas, and present sankharas in turn condition future sankharas. If past sankharas were 'kama chanda' it is likely that I engage in the present in such a manner. Suppose I do, isn't it possible to cleanse present sankharas during meditation (after some while) in order to concentrate the mind, resulting in seeing things as they are ('vipassana)?
