We find profiles >5yrs old but still saying firsttimers. Assuming these PPL login regularly nd are not so bad that can't find a match the only reason will be that they didn't bother to update profile. So why won't u keep profile up to date?
So far we feel reasons are-
a) You don't believe PPL read or care about profiles pics are enough?
b) You really got nothing to tell or trying to be very discreet?
c) You nyway have pics worth thousands of words...lol
d) You simply being lazy
Also most gentials looks similar so I am not sure what purpose it serves to put close up of those bits as main pic?
Having said this we often meet nice PPL with nothing much in profile.
