why do u think that not having a gf at the age of 21 means
theres something wrong? is it cos of peer pressure? or ur parents
hounding u? or some personal issue?
anyway it certainly does not mean theres something wrong wif u for
sure. but still, u may wish to consider ur social circle, whether u
have been too introverted, the way u carry urself, etc. talk to
close friends and seek their opinions lor..
in the end, its not the end of the world not having a gf. not
having one is definitely better than rushing into a relation and
finding its not the right one for u
