Thank you for the responses.

This is my second child, though the first I'll carry while practising any aspect of this lifestyle. I think this will help me know when my body is trying to tell me "Enough." My fiance has also been very good about respecting my voiced limits. If I tell him stop, he stops. I think right now while we are learning, it helps that I'm really too independent a personality to ever make a good "full-time" submissive. It keeps us from going too deep into the mentalities before we're ready, which mid-pregnancy-hormones, is not the best time to start.

And (I think) because the play is an aspect of our relationship, instead of the other way around, the necessary trust is already in place. And I've already had the taste of the joy a sub can feel in knowing her Dom is happy with her and trusts her. We were playing last night, and just the satisfaction I got in cradling Him after and knowing He trusted me enough to lay His head on my breast and go to sleep, I have a hard time describing it.
