I'm Not Sure If I Should Get Side Swept Bangs.

I'm not sure if I should get side swept bangs. I usually part my hair in the middle, but sometimes to the side. I have longish hair that is medium thickness that is straight. I'm 13 years old. Also, how can I prevent acne on my forehead if I have bangs? I know it can hide things but I don't want an oily acne covered forhead hidden by strands of sweaty hair!! What are some preventions to this? Any advice would be wonderful!
