I get really turned on by my girl mates and want to try stuff out with them

I get really turned on by my girl mates and want to try stuff out with them but I dearnt. I also masterbate once I have seen them or once they have stopped, as I'm always turned on, I am completely straight as my boyfriend makes me wet in seconds and brings me to orgasms in seconds when he's just playing with my clit. But my problem is how do I tell my girl mates I want to finger and eat them out?? And how do I go about telling them that I masterbate over them! X
