Your desire to get married and not have any kids might be considered a taboo in the olden days, they might think that you are somehow not normal to make such a decision. Just like in the past nobody can come out to say that they were gay, it was a taboo, it still is in some cultures. But in this age people are more open about their desires and I've heard people like you who don't wants to have kids and we have to respect everybody's decisions. As a man you have to find a woman that wants the same thing but I don't think that it'll be easy to find because most women will like to have one or more children at some point in their lives. I wish you luck in your search for your perfect match, I want to believe that a woman is somewhere also looking for a man like you.
