This question is not totally clear to me.
You seem to want one word for two different things.

1.) Enjoying to be with a crowd is something quite different from enjoying to be before a crowd.
2.) To go where people gather or to go on stage where people watch you, are also two different things.

*A person can enjoy being in a crowd but be scared to death if he/she would have to face that crowd.
*A person can love to go where people gather but be too shy to ever go on stage and have people watching.

Some people may feel happy in both circumstances.
But then should the 'or ' in the question not be replaced by 'and ' ?
