I'm not sure it's a euphemism. But a synonym for doorman can be gatekeeper
It is a adjective relating to someone using euphemisms. So someone could be "euphemistically speaking".
A euphemism for "maniac" could be "enthusiastic individual" or "highly energetic person." These phrases soften the connotation of instability or extreme behavior associated with the term, presenting the individual in a more positive light. Such euphemisms can be used to describe someone with intense passions or interests without implying negativity.
shameful or embarrassing
The word you're looking for is probably taboo, or something similar. But the validity of this statement is debatable.
Some people think that by using euphemisms to describe genitals they are sending a message that somehow they are bad or are something to be ashamed of, while other people feel that using these euphemisms gives the children names for their body parts that are either cuter than the technical name, easier for the child to say, or more often it gives them a name to use so that is less socially awkward. Adults know not to yell out that their penis itches in a mall, but a small child doesn't know/understand the more intricate parts of social interaction.
Also, speaking as a doctor, most adults don't use the 'correct' terms to describe their genitals. I have very rarely heard adults use the words anus, rectum, introitus, labia, perineum, glans, corona, etc. They very often will use euphemisms like butt, dick, or other things that are more vulgar. And then even when they are using the anatomical terms, they use them incorrectly. Many adults don't even know what their glans, introitus, raphe, etc. even are, much less how to use them. So in reality, they are substituting their euphemisms for others.

Why do women use Healthy as a euphemism for being Fat?
Many women are sensitive to the fact that a lot of other adults (including many of their friends, no doubt) are overweight. Women who are naturally thin or who lose a lot of weight may not want to offend their friends by saying that they lost weight because they didn't want to be "fat." So, instead, they say they wanted to get "healthy." But if they are eating more vegetables and fruits AND they lost weight, they most likely ARE more healthy.
