Should I be in a relationship with a very young but willing girl?
Probably not. Why do you go out with such a young girl?
I'm man enough to be satisfied by a woman who weighs only 99 pounds
Your relationship with a young girl is wrong on so many levels, you should date someone your own age instead. Dating a minor could result in criminal charges.
I know it is wrong, but god she is tight.
That is no excuse. You should date people who are around your age range. Dating someone who is significantly younger or underage is not looked at kindly by others.
