If sui should I be leaking urine between legs when coughing?

Yes. Subjects with stress urinary incontinence can experience urinary leakage with coughing, straining, sneezing, laughing, jumping or going down stairs.In fact whenever there is a sudden increase in intra-abdominal pressure.This pressure is transmitted to the bladder & leakage occurs when intra-abdominal pressure exceeds the urethral closing pressure of your urethral and bladder neck sphincter muscles.
