Hi. I transfer to the toilet and bear down and push with my stomach. I started doing this about a year after I was injured and it helped me keep some upper ab muscles.
I actually put some oat meal in the microwave for 2 minutes this morning and went to pee while I was waiting. The microwave timer went off around the same time I was done pulling my pants back up. I drink about 1 gallon of water a day so my bladder is usually full and ready to go so it's not hard to push it out. I push a little harder when the stream slows down just to make sure i'm getting everything out. I pee a lot since I drink so much. Probably pee 12-14 times a day. Unfortunately, I'm going to a party at a friends house tonight and their bathroom is not accessible so I'm taking a catheter and a large water bottle to pee in while I'm there...
