Im 32 and same issue. Went to doctor for an ultrasound because im a pilot and cant pee at work. I since learnt to sit down to pee, lean forward, and push into your bladder with your fingers. You can even kindve do it when standing up. I end up doing a second wee. This takes a few seconds longer and its helped me so much in life.
I dont have an answer to the question though haha
