Sexual fantasies can reach greater heights if a man can prolong his ejaculation. Sustaining ejaculation can also help in attaining greater satisfaction for your spouse. Unfortunate though it seems, many men suffer from premature ejaculation which is a failure in prolonging the ejaculation and attaining full climax. Premature ejaculation is more common among older men. However, it is also not a rarity among the younger generation of men.
