Pelvic floor exercises might possibly help. See the video here:

Keep a check on how much fluid you're drinking. I had some similar problems recently (as a result of side effects from radiotherapy) and realised that part of the reason I needed to go to the loo so often (for both 'standing' and 'seated' functions, as we guys see it) was that I was drinking far more than the recommended two litres of fluid per day. (I was probably drinking closer to five litres). Cutting back my fluid intake, to closer to two litres, has helped a great deal, both 'at the front' and 'at the back'.
