Help?

Akila

So..I'm 16 and my fantasy is being dominated, my boyfriend knows I like to be submissive but I don't think he knows to what degree. I want him to punish me if I don't do something how he wants me to, I want him to pull my hair, pin me down, choke me, and treat me like a little pet of his...I know that sounds a little intense and I'm super insecure about it...How should I tell him I want more? First of all, he just starts going and doesn't really do a whole lot of play to get me excited...I usually suck him off or give him a handjob but then I'm never really enjoying myself because that's really the only thing that turns me on. What do I do?
