Code Reduction for Multiple Inheritance

Question

I wrote a small little program in which you type a boy or a girl, and prints an expression. My main question is that from my code there is an easier way to write for women next to copy and paste from the base class. Here is my code

#include <iostream>
#include <string>


class Man{
protected:
    std::string name;
public:
    void getInfo(std::string hName){
        name = hName;
    }
    void showInfo(){
        std::cout << "Your name is: " << name << std::endl;
        std::cout << "And you are a MAN" << std::endl;
    }
};

class Women{ //is there an easier way to write this         
protected:
    std::string fem_name;
public:
    void getfemInfo(std::string fhName){
        fem_name = fhName;
    }
    void showfemaleInfo(){
        std::cout << "Your name is: " << fem_name << std::endl;
        std::cout << "And you are a Women" << std::endl;    
    }
};

class Human:public Man, public Women{
public:
    Human(){}
};

int main(){
    //local variables
    std::string choice;
    std::string tName;
    //declaring objects 
    Human person;
    //user interface
    std::cout << "Please enter you name: ";
    std::cin >> tName;
    std::cout << "Are you a [boy/girl]: ";
    std::cin >> choice;
    //if handler
    if (choice == "boy"){
        person.getInfo(tName);
        person.showInfo();
    }else if(choice == "girl"){
        person.getfemInfo(tName);
        person.showfemaleInfo();
    }
    system("pause");
    return 0;
}

When I try to get a class Womanfrom a class Man, it makes person.getInfo(tName)it person.showInfo()ambiguous. Why is this? And how can I make this code smaller (for women).
