I dont know whom you met and from which religion. I have friends from various other religions and from across various countries. We had lot of discussions on Hinduism and other religions. But no one asked such questions like whether a lingam is a DICCKK???
Since you end with Jai Hind means you must be from Hindustan and if it is true then you should know the answers to all your questions. If not then that means either your parents have not tought you about the Hindustan and its culture or your teachers might have had sold themselves to the missionaries or you must have been a student of MADARASAS.
So do not panic and try to find the answers by yourself. The answers are very easy and you will get them in no time if you look for. GOOD LUCK!!!
