My son was about 8 when he started dancing. All along we have stated to him that it is up to him if he dances or does not. He knows it too that he can quite if he wants to. I think giving him this 'power' has made him want to dance all the more.
He is very proud of the fact that he dances and has run across a few good male role models for him to look up too. When he attended dance camp this summer, one of his hall mates was an 18 year old male that danced at his High School Graduation party. He stated his friends had alot more respect for him when they saw him dance.
At the sametime I have witnessed clearly a young boy being forced to dance by his parents. His self-esteem was so low that it was pitiful.
We try to reinforce to our kids that they are dancing for themselves and no one else. They should enjoy it, have fun and make new friends at it - which they do. At the sametime we insist that if they choose to be in dancing, then there is an expectation that they will practive!
