As soon as I read this, I immediately thought of... the turtles mating lol. Turtles "flutter" their claws and swim all around in circles of the female to..um 'invite' (?) I guess, but if the female doesn't wanna, a fight will start. So if you dont want little turtle-ings running around, I suggest seperating them.
However, if they are both male, they're obviously not gonna mate, but like Steve said, males are more aggressive and territorial and is probably a good idea to seperate them now, before anything... bad happens. For basking area, you can make a ATBA (Above Tank Basking Area), if you are the DIY type. Just search anywhere, and you will find loads of information and pictures.
