Do guys care about age?

A strange guy I never had a single conversation with kept sending me super expensive gifts on neopets which is a digital game that uses virtual money and not real money, and the neopoints do not cost money to buy, but they cost time to earn, then I added him as a friend so I could remember to buy him gifts as well, since I always repay people who buy me things, and after we added each other, we had access to each other's ages online and I never heard from him again.

I also remember when I was having a normal conversation with a guy at a party and he was nice and polite until I told him my age, and after that, he acted like I was an enemy that he hated. Like I had committed some type of crime by being born earlier than him. I never wanted to date him, I just wanted to talk to the most intelligent person in the room because I was bored there and he was the most intelligent person in the room.
