“Why am I still single??”
It’s amusing sometimes how people whine about why they don’t have a boyfriend/girlfriend… and then their profile page is set to private.
If you want people to know you exist, make your profile public. 
(If you’re not against love blossoming over the internet, that is.)
Just my two cents anyway. Just be strong enough to deal with the perverted, and have the common sense not to reveal vital information.
