Rules vary from place to place - not sure about Kentucky, but here, I can suggest and even ask someone if they want to be Freemason. I understand it can be hard to ask, but start with simply asking about Freemasonry rather than "can I join?". If someone said it was not a good fit, they might be right... but before I joined I asked around - several were very enthusiastic and one brother I know said it would not be for me - over 13 year on, he was wrong, but he was also not from the lodge I joined... You need to make your own decision...
Why dont you think it might not be a good fit for you, why does that enter your mind ? This is a good place to ask questions.
In most places, we ask the same things of a potential candidate, and I start with them once they say they want to join.
Do you have a belief in supreme being ?
Do you have any criminal convictions ?
Are you male and over 18
Can you afford it (about $350 here per year, and some lodges have a joining fee, and you pay for dinner here, one lodge $20 per night, another $45 - but check in you location, it is often cheaper in the States).
Are you willing to attend (we meet once a month, but again in the States you might be meeting more often, sometimes once a week).
Why do you want to join? (important, if you say I want to join a org to take over the world, I will know you are misinformed LOL)
What do you know about Freemasonry ? (again important, if you think we are a global conspiracy or devil worshipers, you are not going to find what you are looking for....)
Do you know someone who might propose you.
We ask more, about where you live, what your wife thinks of it, if you have the time (here about 4 hours once a month, but the reality is to develop and make friends, you will spend more time on Freemasonry - yesterday I spent 6 hours LOL, but I'm involved in all sorts of stuff - BY CHOICE)... I tend to tease more out, esp about the character of an applicant exploring his heart and attitudes, especially on tolerance..
All these are to qualify you, but also to help make sure you will be happy and enjoy Freemasonry...
