This is a condition where a man needs a time period of over 30 minutes of sexual stimulation to reach orgasm or to ejaculate. Delayed ejaculation refers to an inhibition of ejaculation. The man is unable to ejaculate, either during intercourse, or with manual stimulation in the presence of a partner. Most men ejaculate within 2 to 4 minutes after onset of active thrusting in intercourse.
If it's really that important, move it to a "List of Atypical Masturbation Aids" page or something. It can only serve to confuse those who don't already know what masturbation is. I thought it was a joke when I first saw it. Clearly others did too, as it was previously removed for supposed vandalism.
