Longer Lasting

Is this a problem i should be thankfull of, when i have sex i just cant seem to cum and it takes a lot longer than i think it should i could go for over an hour before i cum and im not bragging by the way. I dont suffer with erectile disfuntion or anything or is this normal of a man of my age (50) i have suffered with this problem for about 5 years now look forward to reading some of your comments Thanks Steve

Becoming de-sensitised is frequently listed as a consequence of using a 'heavy-handed' masturbation technique with more pressure and/or speed than can be matched by conventional sex. Perhaps it would be worth going without any sexual release until you are almost biting the furniture in frustration and see if the problem happens then.
