I need help finding the title of this manga.

Sorry if the description is a little vague.
Well, a young boy travels to some country where it is just desert because his older brother's lover has called him there because his older brother has gone missing and the lover wants the younger brother to become his new lover as punishment for his brother leaving him.

Also, I am looking for another manga where a boy travels to a country where it is also a desert and he climbs a pyramid or somthing like that while touring. He and another man fall off and they switch bodies. Then the boy gets take by a prince because he thinks its his lover.

Hope that helps.
Thanks in advance!
