"If" statement gets ignored when function is recalled

I am trying to create a simple program which will ask the user to input an age and then will ask the user to input another age to find the difference.

The problem in my program arrives when I ask the user to confirm their age. When I ask the user to confirm the age, if the user answers confirms their choice, I want the program to keep running. But currently, I am stuck in a cycle which even if the user inputs a confirmation, the program skips my if statement and always runs my else: statement.

#This program will prompt you to state your age and then will proceed to
#calculate how long till __ age

print("Hello. ")

while True:
    try:
        myAge = int(input("Please enter your age: ")) #int( makes func be a #
    except ValueError:
        print("I'm sorry, please enter your age as a numeric value.")
        continue #Continue function loops back to the function making it 'continue'
    else: #If it is a # then it breaks 
        break

#Going to ask for the second variable
print("You are " + str(myAge) + ".")
print("What is your desired age? ")
 
def secondV():
    desiredAge = int(input())
    print("You wish to be " + str(desiredAge) + "?")
    yourWish = input()
 
desiredAge = int(input())
print("Do you wish to be " + str(desiredAge) + "?")
yourWish = input()
 
def choose():
        if yourWish == "Yes" and yourWish == "yes" and yourWish == "y" and yourWish == "Y":
                    print("Okay... calculating")
                    print("To be " + str(desiredAge) + ", you would have to wait " + str(desiredAge - myAge) + " years. ")
                


else:
        print("Erm... please input your desired age now:")
        secondV()
        if desiredAge == 'yes' and desiredAge == 'Yes':
            print(Yes())
        else:
            No()

choose()
print('Goodbye.')
