Regarding the problem of how to be aggressive on Sankirtana and submissive in the temple, my request to you is that you should go on being aggressive on Sankirtana. I myself was aggressive in coming to your country. No one invited me. Even you boys and girls did not invite me. But, I came and I preached aggressively, and therefore you are now my disciples. So now you well know you have to approach the men and women of your country, and it may appear that superficially that you have to disturb them. They are doing their business peacefully, and you come and disturb them, "Please take this Krishna book."
Of course it is good that you are concerned about being chaste, shy, and submissive amongst your godbrothers. Canakya Pandit said that every man should see all other women as mother, and similarly a woman should see all men as son. So what is your difficulty? If you are completely aggressive on Sankirtana, there should be no material aggressiveness and pride remaining. You have to distinguish between devotees and non-devotees.
Aggression for the cause of Lord Caitanya Mahaprabhu is pure. If you become completely absorbed in such aggression to spread Sankirtana Movement, there will be no question of wanting to lord it over in the temple. Preaching purifies us of these material tendencies for sense gratification. It is simply a matter of time that you will see this. Do not worry. Krishna will help you.
