Sure. Some examples are:

* The double standards and expectations placed on men, e.g., the idea that masculinity implies being physically strong and mentally strong and emotionless, or that they should always be the breadwinners for their families.

* Limitations for men in terms of how they can express their gender. Men who do not conform to traditional masculine gender roles may face discrimination, stigma, and even violence.

* Men may also face discrimination in certain industries or fields that are traditionally dominated by women. For example, men who work in early childhood education or nursing tend to face discrimination or stigma.

* Men can also be victims of domestic violence and sexual assault, though these issues are often more commonly associated with female victims. Especially true if the men being victimized don't conform to traditional gender roles.

I actually experienced the discrimination in the workplace once. I was turned down for a job because of it. I have a kinda weird sounding name, so on paper they thought I was a woman. It was a for a holistic medical clinic as a front desk worker, so pretty basic administrative and clerical work. I was brought in for the interview and it turned out to be a large group interview (which are the worst). I was the only man in the whole room. After getting called back for a second interview they told me that I was a great fit for the role but they had some employees that were uncomfortable around men. Which to me was interesting because this clinic served both men and women, so its not like only women passed through here. Anyway I was told no hard feelings but I couldn't work there. 

My whole career i have been doing customer service, administrative and clerical work. Aka a lot of the same stuff a secretary would do. Im almost always in female-dominated workplaces if I can get a job in them at all. Idk why it is seen as work for women, I have never thought of my job as relating to my gender at all. Almost every job I have had for the last 7 years I hear "It will be nice to have a guy around to break things up" because thats just how few men I work with.
