LUST = SEX = ORGASM = FLEETING/TEMPORARY SATISFACTION.

From my perspective (as a WOMAN), I prefer intimacy coz it makes a couple more connected in terms of mental and emotional aspects.

SEX is SEX and it's that...JUST SEX. After the ORGASM or the RELEASE...what comes next? You roll over to the other side and SLEEP? EEEWWWW.
