I'm not sure if this topic should be categorized under "Safety". Mods, feel free to move it if you don't think so. Thanks.[/quote]
Of course your question is in the right thread Steffy.
Anything which is done to you in a play situation should be such that no permanent harm, disfiguration etc is caused - that is, unless you specifically want that.
Yes, of course things like urethral stretching and other activities, if carried out to excess, can leave permanent problems. Carried out sensibly and with pleasure in mind such activities cause no harm.
Agree with your playdoc beforehand what is going to happen - enquire off others if in their opinion its wise. After all, when you're in the throes of being pleasured its pretty hard to keep a straight head on your shoulders.
Above all use an experienced and respected playdoc - read their posts and profile - ask them for references from established zity,biz members and take up those references, directly with the referee, before you agree to anything.
Play nice - Play safe
