Remember, baptism symbolizes your dedication to Jehovah. It would be assumed by others that if you were baptised you dedicated yourself. However, only you would know if you truly dedicated yourself.
When I was about 14 or 15 my father told me he felt I was ready for baptism. As an elder, he would get in trouble for saying certain one were not ready and he was usually right. He told me I should tell the Presiding Overseer I want to get baptised because a Circuit Assembly was coming up.
The next meeting I went to I was shocked as the Presiding Overseer came up to me and said,"Your father tells me you want to get baptised. Is that true?"
What was I supposed to say?
So, I never dedicated myself. I did it because I didn't want to piss off my father. Therefore, I was never dedicated.
