No necessarily that the male will be mature, males mature at all different sizes, my friend has a 14cm M that is not mature yet.
could still be a while for them.... Also like the others said very hard species to breed to the females love to eat the males... But im glad you being ambitious and trying a great spider who knows you might pull it off... if you know the basics of breeding.. and i hope you do succeed... :happy:
