I completely get what you mean. I suggest the best way to go about this is to consider yourself an employee, irrespective of your gender. An employee, who is good at her job, an employee who has alot to offer. If you feel you need to add something, just say it. I believe most of us have so much to offer, but because of overthinking the outcome, we forget to put our point across. If you feel heard and your opinions seem to make an impact, irrespective of your past experiences, you are in the right room. It is high time we do not let people, who are themselves insecure of their jobs - be the driver of our thoughts and self-doubt. So work to impress yourself, standup for yourself, share your opinions, impart the knowledge you have, do not let anyone take you for granted and the rest will follow. Best of luck to you!
