hello MADAM... this is not abnormal. The vagina is no designed to collect all that semen. Its like a long glass top with a very tiny hole at the bottom.when he ejaculates ,only very little will go through especially the sperms who can swim up into the cervix to go fertilize an egg.in summary, the back flow of semen is not abnormal. It must flow back and it doesnt stop pregnancy from occuring.if you are having trouble after one year of trying,you and your husband have to see a Dr together to get tested.
