How to acknowledge emotions and their consequences in day to day life? Do you have any suggestion on how to view the act of sexual intercourse objectively? For example, when we view a lady, we view her as a composite of flesh, bones, feces, pus, joint oil, etc.

Similarly in which way can we address sex neutrally without labelling it as good or bad? This is because I have learnt to remove my lust for the human flesh, but not for the sexual act. Is there any thought based method using which I can achieve this feat? Similarly while using urge surfing, when a lustful desire comes up I repeat in my mind "pleasure, pleasure" -- similarly how can I combat a desire to have sex through this technique as I am on a period of abstinence?
I see you have accepted an answer but i feel like to add something because I can personally feel related.

Do yo mean like you learnt to let go of the ice but still desire its cooling property? 

If so, that means you can let go of rupa (form) but stuck at kama sanna (perception of sensual pleasure).  Perception of grossness of body may not help with kama sanna because you are already above Rupa and dealing with something of a higher level.  

So many ways to deal with kama sanna such as meditation.  I promise you it will help.  

FYI: I recognize a pattern for terms Buddha used for satisfactory in sensual pleasures; kama chanda, kama raga, kama sanna, kama yogi.  Each has specific use and definitely not interchangeable.  For example, when Buddha taught about sensual pleasure in 5 hindrance, or jhanna, he would use kama chanda, or kama sanna.  Howerver, when he talked about higher fetters or an anagami, he would use kama raga or kama yogi.
