All the Dr.'s say regarding sex is to expect some blood in the semen for up to a month. Most say wait at least a week for sex, if not longer.

The coffee, tea and juices are just common sense as the procedure can impact the bladder too. Soda is just as bad too. All these irritate the prostate and bladder, so it just makes sense to take a break and only drink pH neutral fluids during recovery, water being best......tbh, I've never drank so much water in my life as this past week.
