Are your partners experienced in BDSM?

They should know CPR. They should know how, and when, to check the bonds for adequate blood flow. They should know what sub-space is. They should know what after-care is and how to use it in relation to your specific needs. They should know basic first aid.

I will just comment that we all think we are mature at the time we think it....I thought I was at your age (and every age after about 12...). Now I realize that I was not. I knew nothing of the psychological consequences of actions when I was younger.

My opinion (since you did ask and, so, I assume you mean you want honest opinions rather than just approval?) It is not embarrassing to want whatever you want. I think that it can be physically and psychologically dangerous to act on what you want at your age.
