I know women do this too, but I can only speak from my experience of having ran into men lying about their ages, so...
I once had a guy contact me on a dating site who was using a picture from when he was in the military, so when he would PM you, an avatar of a young-looking guy would appear onscreen (but it was blurry and small enough that you couldn't really decipher the details.)
In reality, he was over 70 years old (and at the time he tried to contact me, I was around 33.)
I've also ran into "mothers" on dating sites who are "looking for a nice girl" "for their sweet, unmarried son." I have no idea what all that entails, but I found out about at least one who was indeed looking for a girl for her "nice, sweet," incarcerated boy... who was still behind bars.
Now, I'm not saying people in prison are without hope at all. I'm just saying... I was a bit shocked at the time.
Best wishes to you, Hellooo, and hope you enjoy your date!
