Totucgender is a gender identity when one feels 100% like a select gender all of the time, but one occasionally experiences minute amounts of any different gender(s) on top of that. The gender(s) on top of ones dominant gender, when they're there, do not change the fact you feel 100% that dominant gender. Although, they do still add on. For example, feeling 100% female, but added on top is 5% agender and 2% male.
