Hothouse saidI will add that the blue pills will help you get and keep an erection - they don't do anything for your libdo.
They don't necessarily make you hornier. Getting hard, really hard, might make you horny though.
If you're experiencing decreased sexual desire, they don't help with that.
eb925guy is right - older guys don't get erect as quickly, and some don't get as hard, or stay as hard, as when they were younger. The pills do help with that.
I don't have an issue with getting an erection, but after reaching the big O most times I go soft (unless the sex is REALLY good, then it stays up.) Using the pills I stayed hard after cumming. For a long time. Long enough to cum multiple times.
I got a script for Levitra. Just a half dose. (and it's a tiny pill....hard to split!)....good for 3 days. But it's very subtle and transparent. One thing I noticed is I can control the erection better and longer. I don't "just cum"....but if I miss the first quickie "wave" I'll go another 30 minutes, or then an hour, etc. Before never a problem getting it up or keeping it, now it's the quality of it! I was always a "roll over and take a nap" when I was done type, now I look for a 2nd, or 3rd sometimes.
I still don't need it, but mentally I know it's better sex. Yet one time I was out of the 3 day window (thought I was still "in" it) and had a great time. So some of it is psychological.
