Explaining to your children that you have sex.....

I have grandchildren that are under the impression that I shouldn't be having sex! LOL If they only knew. My adult granddaughter found my toy box and began asking a load of questions. So of course I gave it to her straight. So now I am getting all these calls at the oddest hours with her asking me about sex. I suppose her husband is benefiting from my knowledge and experience! Or maybe its not her husband......I just dont know. After her last question though.....(she wanted to know what size strap on to get.) Well one things for sure....that apple didnt fall far from this tree!
