Hai silvia,
What is the difference of famous/unfamous.He is a man. Is it not?.whether you afraid about his fame? Are you feel inferior for that fame?
otherwise you feel unsecure by his popularity?
Why do you feel guilty about your dating?
Did you like his company or not? Why do you worry for others?
Yor heart is the right judge for you.
Have a nice dating experience and be happy.
