One of the taunts my ex made to me was that this younger student "had a curved one." Whether the curve or his endurance (she also taunted that he claimed he had to go an hour before blowing his load) was the driving appeal (or both?) I don't know. I was in denial so I dismissed her taunt, but he was pretty effective, and repeatedly cuckolded me for two years.
Just to be clear, the ex several times revealed her attraction to any erection displayed to her (on offer). That she taunted me with one guy who made a cuckold of me having a curved erection was in no way meant as disparagement. Whether his curved cock really his her just right or not I don't know. But the fact is that he cuckolded me with his tool for two years. So kudos to the curve!
