Is it possible for this guy to be a "player" according to his natal chart or is just not going to happen?

You want honesty... NO chart will tell you what kind of life you will live. That is a personal choice you will make everyday you wake up. The next few years you may wake up wanting to get a new girl in bed than that will happen. Don't be surprised if one day you wake up wanting to start a family. Its all a personal choice you make everyday. If you don't care about STDs just having than that's what you will do. Enjoy it just be careful because if for some unfortunate event you do end up with STDs and you spread that knowing you have it the cops will bust up your plan to "live your life by sleeping with lots of different women" So it pays to be cautious!
