Hi Penelope,
Guys can be on the receiving end of so many messages from fake dating profiles on a dating site that they reach a point where anyone they see who is even halfway decent in appearance could easily be a scammer.
They ask whether you are real to be certain that you are before they begin to invest any valuable time and effort in chatting with you.
You don’t have to wear makeup or dress sexy to appeal to guys. Guys are drawn to features and as long as they can clearly see them, you don’t need makeup or a sexy dress to capture their attention.
As far as being asked for hookups more so than potential relationships, it may come down to the dating site you are using. POF is a free dating site. Something free can be easily abused by people who aren’t taking online dating seriously and are merely looking for hookups or some time to kill.
