Urethral flaring

By default, the male urethral opening is quite small — primarily to enhance the penis's ability to spray urine and semen with adequate force and distance (sort of like how water sprays farther when you squeeze the end of a garden hose).

However, some men prefer a urethra shaped either like the end of a trumpet (see: trumpeting), or, if they have a meatotomy or subincision, flared open. This goal can be achieved through surgical removal of the glans around the urethral opening, generally through use of either a modified clamp and cut procedure or a cautery tool of some sort, creating a urethral flare.

Urethral flaring will very slightly shorten the glans of course, but it should have little functional difference other than some reduction of ejaculatory distance.
