To your own self be true, Serenitypup. If pulling back is what is the best for you, you should do it. However, Oz has a very good point--the forum can be a very supportive place. There are lot of threads and folks here with helpful information and advice. You might be able to learn things that will assist you as you move forward so that the next time you go swiming in the pool, your experiences may be more positive.

And you're right, a true Dom will respect you and your limits.
