Im a boy 13 and you want to become a girl because they are in demande of boys should you have a sex change opp or is this just a phase?

Answer

At 13 you are too young to think about a sex change. A sex change is very expensive and takes several years since doctors have person who wants to do it live as a woman for a time, take hormones, and go through psychological testing and counseling. This is not a surgery that can be changed if the person decides they were wrong. It can be very confusing to be 13 because you are just learning about who you are as a person and who you are sexually. Give yourself time and age before you think about doing something like a sex change. I would say now your reasoning needs a bit more thinking, consideration, and it is a phase.

Second Answer

It is possible to realize that you are transgender at the age of thirteen, but due to the cost, permanence and complexity of sex change operations it is still recommended that you wait. It is not an absolute necessity to change your sex if you identify as a different gender either, and there are alternate types of gender expression other than just strictly male or strictly female. It is possible that this is just a phase, but you are the only one who is able to truly tell, so in any case it is recommended that you wait and try not to allow yourself to be too influenced by other's opinions.

You also are saying something about wanting to be a girl because they are "in demand" of boys, which is not a worthwhile reason to change your sex. If you are attracted to boys you should probably this is probably what you want to focus on discovering your sexuality rather than contemplating changing you sex.
