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?
