Wanting to Purchase Snake
 

Hi,
I am new to the snake world but not animals I grew up on a farm with cows horses dog etc. I want to expand my journey into snakes as I financially stable and own my own property. I have been doing research but it is much easier to talk to people with experience via reading websites. I am very open to what kind of snake I should look into. The Boas have caught my eye because of the larger size of the overall animal I would like to get a snake between 3-6 feet. Color does not matter. I would like to know the pros and cons vs male & female. Also the temperament of different snakes. (yes, I know it all depends on the upbringing and the owner). but since this a new world for me I figured I would ask. I would prefer non Venomous as I am inexperienced with snakes and I have a XXL American bully dog.
Any replies would be awesome, and appreciated.
