I'm talking to two really good guys at the same time
Do you want anything serious with either one?
In some way, I'm just playing with them, I just want to have a little bit of fun
It is good to have fun but it can be dangerous to have fun with two people at once. It will lead to hurt feelings and maybe more.
They know I'm talking to other people and I am not ready to settle down just yet.
If they know about intention then I guess it's alright to talk to two guys at a time. You have to remember it can get complicated if you fell for both of them or one of them for you. So you should be careful about it.
