My children are almost grown at ages 18 and 15 now. Those of you who know me know that my sons are my "mini-Doms". Their father died in an auto accident when they were very young, so we have a very close relationship. I have spoken openly with them about sex since they were 11 or 12. i don't flaunt my choices in their faces, but i have raised them to understand that just because someone makes different choices than they would, no matter what area of life it's in, does not make that person wrong. I am proud to say they are very open-minded, non-critical children and come to me with everything they want to know about.
As for parents and/or other friends, i believe i stated in another post that they are on a *need to know* basis. Not everyone has to know what it is that i need. If you think about it, you don't normally go around chatting about your sex life with your parents, be it vanilla or other (or at least i don't). So i don't see the need to tell them what happens with me behind closed doors.
To those of you with younger children, i'm a firm believer that if children are raised seeing you act a certain way, to them, it becomes *normal* and not something they think about. If it concerns you, do what most parents end up doing.........rent a hotel room when you can to keep them from hearing the screams, moans, sighs, smacks, begging......whew, almost got lost there for a minute .....hehehehehe
