Should I lie about my age and sign up for Tinder?
Why do you want to lie about your age?
Basically because I want to be as high as possible on the ratings
Wanting to meet and date people is normal, lying about your age to do that is not good. You are starting a relationship with a lie which is not good and if you are too young you could be getting the other person in trouble.
I will tell the truth if they confront me on it.
Even so, you are still lying to them. Some people have specific age preferences when dating and you are misrepresenting yourself to them initially.
