Idk why this is so confusing for people. Sexuality is based on what biological sex you get aroused by. What type of people you're attracted to in a certain sex is irrelevant. You like males who have penises and have masculine features? Cool. You like females who have vaginas and feminine features? Cool. You're bisexual.

You like males who chopped off their dick and have a female-ish appearance? Cool. You like females who have vaginas and feminine features? Cool. You're bisexual.

Having a very specific type for males doesn't mean you're not bisexual. It just means you have a very specific type. You're attracted to an extremely small percentage of males, like less than 1% of all males, but a majority of females. That's still bisexual.
