I have taken Viagra and LEvitra.
I've found that Levitra has less side effects, and less Hype of viagra.
I also only use it for when Im going to have sex with a partner rather than just J/O.
(It's amazing how badly depression/anxiety can affect the dick!)
At $10.00 a pill, I usually conserve (IVe still got some left from about 2 yrs ago). I only take a quarter of a pill to half a pill. It still gives me the edge for around 2-3 hours.
But anybody using that drug just to have a 4 hour hardon, that doesnt need it for ED, is askin for trouble.
That's also the common Mis-Conception (even seen in "The Naked Mile").
Some people MAY have an erection for that long, but thats not how the medication was intended to work.
You have to have sexual stimulation to get hard, and it requires your body to tell your dick when to get hard. The medication helps this process ONLY by forcing more blood into your dick when your body tells it to.
When the stimulation goes away, so does your erection. (But, the heart rate, blood pressure, and pressurized feeling does not, for another 2-3 hours)
It would be wise to check your blood pressure before, and then after taking it just to see the side effects it has on your body.
Anybody that may be a heart patient candidate (Like myself) quickly find that it's a no-no pill for recreational j/o fun.
I know I sound Hum-Drum...but rather than having somebody on here OD, or be permanently disabled from it... I'd rather speak out.
