Maggiedoll,
While not into BDSM or hypodermic injections(I prefer to give/receive medications rectally and vaginally) being I do not enjoy giving or receiving pain. I do know that there are those who consider themselves full time submissive coupled with med play all the time. If that is what you enjoy, there is absolutely no reason for you to separate med play and submission, the key is selectivity...period. If you are selective, no matter how long it takes, it will be far more rewarding and more hassle free in the long term.
By definition,being a recipient of exams involving gyno,rectal/vaginal temps/exams,enemas,breast & testicular palpation,urethral catheterization/sounding and other procedures; always requires a specific degree of submission in order to be performed, which in turn requires complete trust and respect on both sides of the equation. If that does not exist, for me, it is not going to happen.
For me over the years, I have been involved with a number of ladies who wanted/enjoyed & preferred complete submission with out BDSM(most with definite medical fetishes that fall into our realm here). In all situations,the med play was ongoing whenever we had the time. In all situations,the med play was shared alternately by both of us, sometimes giving and sometimes receiving,always gently and respectfully yet in control of the other which required total trust in the other to not willfully do harm. Interrupted only by the need for us to go to work and other like in kind items of daily living.
I have found that dominance/submission/discipline can be achieved without being bound or binding another, without be being either masochistic to oneself or sadistic to another. It is a wonderful thing to be able to do that and let completely go when you are with the right person.
I hope that you find something helpful and useful in these thoughts on gentle,complete & total submission I have presented. If not, that is alright, keep looking. If you have further questions I can answer, I use ICQ, the number is in my profile.
P.S.
There was one exception. A lady and I had known each other for a total seven years, had been living together for one. One night while I was receiving, she willfully crossed the boundary and started to abuse. If allowed to continue, it would have resulted in severe physical injury to my rectum. I put a stop to it and terminated the relationship immediately, no second chance. Remember, always know the boundaries and stop points,it is ok to be dominant,always be...gentle...gentle...gentle.
