I am 64 years of age but still interested mating wife.But if a gap of one week persists for mating, I occasionally feel early ejaculation. If I can control this moment, I continue for a good long period. Because of this unsure intercourse, I feel of the fear that I may not satisfy my partner .Can you mention the treatment for this type of early ejaculation .I am free from any ailments.Frequently I ride Stationary cycling. Thank you very much,,,
