The first problem, at least to a native English speaker, is your use of the phrase my room instead of my office. Native English speakers use my room most often to mean my bedroom or my hotel room. Your use of room to mean the room in which you work will sound strange to any native English speaker, male or female.
As others have also pointed out in comments attached to your question, we use office to refer to a room that people work in:
Definition of office in English: NOUN
1A room, set of rooms, or building used as a place of business for
non-manual work [emphasis mine]
If we simply say my office, we almost always mean the room (or rooms) in which we work and have our desk. The readers of your messages will know you are not talking about the building.
There is likely a second problem. The form of your message will produce a different feeling, depending on cultural backgrounds.
For most US Americans, particularly, it is considered more polite and respectful to make a request instead of issuing an imperative (command), whether you include please or not. This is generally more true in cultures which more highly value the ideal of social equality among people. Of course, the average American knows that some people are in positions of greater power or a higher station than other people, but we consider it polite to at least behave as if this is not the case!
Also, you may prefer to use only two or three words, but (again in mainstream US office culture) politeness requires a few more in most situations of this kind, whether you like it or not. Many people will lose some respect for you, or think you are not socially intelligent, if you do not understand how to adapt to the situation.
We most often use questions instead of commands in this case, no matter what kind of rank relationship exists between two people. It is understood that the response will not normally be no.
If the person can assume your location, you do not need to say where you are.
Hi Mary, can [or could] you come [and] see me please?
Sandra, do you have a minute to come [and] speak to me?
Can/could you come to my office please?
