My biggest problem is lasting as long as I want to.  Does this community have any wisdom to share regarding tips, trick, methods, or medications that actually work to help a guy last longer?  I am confused about medicines like Viagra, etc. don't they just make you hard, but do they also help you last longer (withhold ejaculating?)

Mastubating prior to a session might help. Using a thick condom would reduce sensation too. There are numbing creams, but not sure you would want to get any of that on her fun parts.

Seriously.  Eating blueberries - and asparagus.  No joke; look it up. Mom was right.  Eat your fruits and veggies.

that are designed to get you to become accustomed to the sensations that lead up to ejaculation.

For me, this consisted of masturbating until I was close to coming, and then stopping completely.  During this period I hold my breath as long as I can while centering my focus on my body.

Repeat this many times for as long as you can, and with time you will learn to control when you come.

Seeing a good and skilled tantrika is also a good way to learn to do this.

Here's a link to a site with many good tantrikas.  Maybe one will be in your area.  There is also a wealth of information about tantra if you want to learn more.

When you feel you are about to climax, pull out and either you or your companion should grasp the base of the penis tightly and hold, about 30 seconds, before resuming.  Then restart.  It's supposed to work!

I actually find not ejaculating at least the day before helps, and then as marketing as it sounds Vitalikor seems to help (and at the least enhance the session). Also def take ur vitamins, exercise, those all factor in.
