Then if the gal likes the guy for years but never confess, never fuck, hints there is some sort of social-class stigma right? probably the guy is less handsome, not richer, not smarter, etcIf both parties just fuck, no need to meet parents and relatives. No need to reveal resume to parents and relatives. No external pressure.
No need to save money for wedding, buy house etc.
For a girl, if the guy is not established in his career and cannot show her parents and relatives, but he has a big cock, can keep him as "housemate"
The term "housemate" sounds very innocent. If you say "cohabitation", then very dirty word leh.
