Im sorry to say that the people who say its 'normal' and just wash or go to the loo obviously DONT experience the same problem.
I have had this before but not to the extent that I have now, with my new partner...it lingers. I can smell it on my hands. He has also seemingly become too tired to be as active with me..I smell during the week..and its AWFUL.
After doing alot of reading, doc visiting..I ahve come to the conclusion that it is an imbalance caused by his sperm and our fluids..Every guy is different..My guy obviously has stronger chemicals in his fluid that upsets the balance in my vagina.
I proved this by making a mixture of 2 cups of water to 1 tablespoon of vinegar, sat on the floor, got a syringe without the needle and syringed 4 loads inside me..
WOW!!!! instantly NO smell and I was back to my normal smell..its been 3 days now and still no smell..
This truly is a miracle for me and I cant wait to tell my partner as I am sure he thinks I am unclean..
Try it...I guarantee it works! But make sure you have no infections first..
