Oh congrats!
Listen to your surgeon! And take after care seriously, it's really rough, especially at the start, but it's very important. Oh, and drink lots and lots of water. I was already prone to UTI's before bottom surgery, but it got a lot worse after. (Now with drinking enough fluids and some cranberry supplements and once I didn't need to wear pads anymore post-surgery wise it got a lot better.)
Oh, and don't worry if everything doesn't magically feel right in every way from the start, it takes time for your body to adapt to the new anatomy + healing + nerve rejiggling and all that.
