How can I keep this under control?

I like to play recrational intermurels volly the only problem though is with the outfitted uniforms... they ask us to wear small "boyshorts' style panties that are fitted through the crouch area.. i am very modest about that area because of my hairs and poof problem.. even in a long pair of biker shorts, or knee length boxer shorts it finds a way to creep/peek out.. is there any way i can keep my bushed poof under control? are there any panties or sprays i can use to keep the hairs from being visible/?
