Kinky tmi!

Ok so I'm a virgin but I'm 100% a submissive. Bdsm just turns me on. I met this guy briefly and have been talking to him ever since. He was talking to me yesterday about licking me out, having sex etc. the only reason I want to loose my virginity now is because the pain mixed with the pleasure will be so good. But anyways yeah I'm not sure if I Should or not, I'm only 16 but I'm just so horny all the time! Also, is fucking in a shower good, because that's where he wants to have sex with me the first time! How do I tell him that I want to be tied up etc etc?
