Suggest Remedy For A Vaginal Condition

I fingured the vagina of my wife with two fingers and applied pressure in upper direction and as a result her size of vagina has increased and now during intercourse she complains that she doesnt feel that the penis has been inserted in her vagina as my size is also not long and is not thick. Please help me my sexual life is ruining day by day and also my marriage is in danger as i am unable to satisfy her anymore
