I have to be honest with you, this isn't one of my area's of expertise. I do know that this isn't a unique problem among men. And from what little knowledge I have on the subject I have been told that premature ejaculation remedies begin with the mind. Thinking about something unrelated to sex can help slow down the excitement process.

Thank you for visiting Grandma's Wisdom and having the courage to submit this inquiry, I wish I could have been of more help.
