A new spray called O-delay has been developed that can stop men ejaculating too quickly. The spray, consisting of a small aerosol of concentrated mace, is sprayed into the man's eyes by his partner at the moment he seems to be approaching orgasm. The excruciating burning pain caused by the spray takes the man's mind off the moment and deters orgasm.
Up to 40% of men experience premature ejaculation at some time in their lives, experts estimate. However, O-delay reduces the likelihood by up to 99%, and can also encourage more vocal lovemaking. Researchers found that if the effect of the spray wears off, another dose can be easily administered, allowing the man's partner to delay climax indefinitely.
The most surprising effect was that after several applications over a few weeks, the spray becomes less necessary. It seems the idea that O-delay may be used, is often enough to control the ejaculatory urge.
Results from the researchers' partners also suggested that in some cases they were able to avoid any ejaculation problems by using the spray when the men had been about to suggest sex.
