I can answer questions related to crushes. I believe I can help teenagers about the problems and difficulties that they have when they get attracted to members of opposite sex. I don't think I will be handle questions on physical relationships and sex.
I am 29 now and I have faced such situations during my teenage and even after that. Based on this, I consider myself adept to be dealing with such situations.
I am an engineering graduate in Computer Science. I have done n M.B.A in Communication Management.
