As a male, I can most definitely say no we are not oppressed, at least not for BEING male. Do we have challenges? Yes. Do we face inequality under the law and social standards? Yes. But we are NOT oppressed.
To say that we (men) are treated unfairly for being male or for male tendencies such as sexuality is synonymous with oppression, because oppression means the exercise of power/control of another/others in a cruel or unjust manner, which is what happens to men all the time, by other men and by women. It happens to women as well? Indeed it does and in the same manner. Oppression happens to men even if it only happens to one man. And not only has it happened to one man, it has happened to most men, and has so for centuries, it has happened to most women, most blacks, most whites, most latinos, and so on and so forth, because that is how people are. But even if it didn't happen to the majority, it still counts because it happens at all.
