Shortly after my wife and I were married, when we took a shower together, she started asking me to help her douche.
This got started, once she realized, my sister taught me how to give a douche when we were teenagers. When she asks about it, I told her, "It wasn't any different than enemas we gave each other. We both liked it, when someone else gave them to us, and douching wasn't any different.” At that, I asked, “Why are you asking, I thought you knew about that?” And she replied, “I did. I just didn’t realize, it included helping your sister douche in the shower. That is, until I accidentally overheard a conversation, between your brother and sister.”
And like my sister, she liked a long-curved douche nozzle insured all the way, holding it where the hose attaches to the nozzle. Once the nozzle was in place, she would instruct me, on how she wanted the nozzle moved around. As a young married couple, it was something we both enjoyed.
