There is also the bizarro version of premature ejaculation, which is delayed ejaculation. This condition means it can take up to 30 minutes of sexual stimulation to reach orgasm, if they do at all. The people at Johnsons & Masters have no technique for people who suffer from delayed ejaculation.
I guess you're mostly talking about penetrative sex here, but edging is pretty cool! (Long as you keep the lube...coming!)
