hi. I am not male but hopefully I can help a little and others can chime in. I use a one piece. I prefer to move everything at one go and have a clean start. The main advantage of the two piece is the base plate says and place, so you are only removing the bag and clipping on a new one. It depends on your routine what will work for you. It is worth getting samples and giving both a try. On the sec question. This article might help. Have you had your surgery or is it planned? Wishing you well. https://bladdercancer.net/living/radical-cystectomy-sex Laura, Moderator, BladderCancer.net
