Why are you hiding your age and or gender?

I used to have an awesome roleplay partner. She admitted to me that she was a lot older than me after a couple years. She had an amazing kinky mind and loved to roleplay but she feared nobody would want to play with an old lady… and I mean old. I could see how a 80 year old woman would love to relive the sexual freedom of her youth and doing it anonymously here was a good outlet.
