A lady’s vagina was erected to clean itself. After the period the cleaning process begins and continues until the coming period cycle. That means it’s drawing itself after coitus and all other types of sexual conditioning involving the vagina. This means that douching is gratuitous and has the implicit to do further detriment than good.
Deeper in the vaginal conduit, past the G- Spot, and right in front of the cervix is the theA-Spot which is just as effective in producing mind-blowing orgasms. Just flash back to use lube since it’s deep and go laggardly so it does not hurt.
