I am very sensitive and had a lot of trouble because of it got teased a lot as a child I also have a very small EGO and struggled with that as well trying to fit in a macho world.
It depends on what you mean by sensitive.
If you mean that you are nurturing, quick to see other's needs and meet them, good at listening to someone in order to understand them better and expand your worldview, and are not afraid to show and express a range of emotional nuance or other "feminine" attributes, then that's great and we need more men to be like that.
If you mean that everything sets you off and therefore everyone has tread carefully around you, then you have some personal work to do.
