2 snakes in one tank??? GOod BAd??

[Jeromerules]

First off I would just like to say I am the proud owner of another beautiful ball python. I got it free with a 100 gallon tank. She is about 3 years old. That is I was told she is a she. Now I have a male who is approximately the same age. My question is Can I put these two snakes together in the same tank? They are both ball pythons. What if the new one ended up being a male or they are both females by some weird chance. Does it matter what sex they are? I just don't want the woman to eat the man which usually happens in life......... ANyways. ANy response is appreciated.
Thanks
