Why do I feel urge to urinate frequently?

It's perfectly alright for a penis to have a slight bend. The truth is that most of the time, this is nothing serious, especially when there is no pain or other problems. This bend could be the result of the arrangement of your tissues or how you use it. However, if your mind is not bothered and no issues are present, then there is no need to stress. 

Generally after surgery, it's recommended to avoid any activities that can put strain or pressure on the surgical site to allow for proper healing. Engaging in sexual activities including masturbation could potentially impact the healing process, especially in the early stages of recovery. Consult your surgeon who performed the surgery for better guidance.
