New guy!!

I met this guy and we get along so well and I've had picked up on him possibly being a freak in the sheets...well I've never had freaky kinky sex .. Just pain old vanilla.. Pretty sad huh.. But yea how do I get over the scareiness of it?? Another thing is since I've gotten older and I'm becoming a young woman adult (I'm 23 btw) and so I'm curious but I'm still wondering if I need a safe word or not lol! Bc I've asked him what kinda freakiness is he into but he won't tell me, and we have not had sex!!
