Ive had phallo, and Id say it doesn't matter if sensation is still coming back, the "urges" are always there. The only time I didn't have them, was the week or so right after surgery where youre just so drained anyway.
2 weeks post op was where I was able to take care of that, so don't worry too much about not being able to do anything. As you can see from what some of the others are saying too, it is possible to carry on as normal
