"Omnisexual and Pansexual are REALLY similar, almost the same. But there is a difference:
Pansexuals can be called "
gender-blind", they do not see or think about
gender, they only are attracted to the person.
Omnisexuals, however, notice the person's
gender, they recognise it and are attracted to ALL genders. "
In other words, omnisexuals are attracted to all genders, but not REGARDLESS of gender. Gender can still be a factor in their attraction, unlike true pansexuals, who don't care about gender.
