If TS being called pervert and not satisfied... probably what TS did was crossing the line already.  The list of actions he typed was NOT WHAT HE JUST DID.

actually, pervert is used to describe a person who likes sexual stimulation and would act upon it in a socially unacceptable manner 

to answer ur questions:

Do u consider as a 'pervert' if u like to see beautiful woman? acceptable

Do u consider as a 'pervert' if u enjoy and appreciate womans look or body figure? acceptable

Do u consider a pervert if u sometimes give compliments to a sexy and hot girl?
DEPENDS. a sincere, hello lady, you look beautiful is good (civilized way of complimenting)
PHEWIT. AMOI AMOI CANTIK no good (more of random catcalling that can seem to be a harrassment)

Or are u a pervert already if u enjoy watching prawn?
social stigma say yes, but newer generation says no
