It's not something I need, but I have tried Viagra and Cialis recreationally and had positive experiences with both. Obviously there's the potential of side effects with any drug, but if you do your research and be smart about it, you can minimize it. I know some will say that if you're being smart you wouldn't be experimenting in the first place, but let's face it, there are those who are curious and want to try it, that's what made me try them. In my experiences the main difference between Viagra and Cialis is the feeling. Cialis feels more like a natural erection but stronger, where Viagra feels like you're dealing with a heat-seeking missile (it will put the erections of your teenage years to shame!). Both of them allow you more control of your orgasm, but with Viagra there's a definite difference where it's a much more powerful explosion, especially the longer you hold out. The key to both pills is to start with small doses, I've found much testimony that says smaller doses can be more powerful and that's been true in my experiences. Viagra comes in a 100mg pill... the best thing to do is cut it in 1/8's... YES 1/8's and start with that. With Cialis, which comes in a 20mg pill, just cut it in 1/2 and start there. I've never tried more then those amounts and honestly I can't imagine taking more unless I actually had an ED condition. Both are very powerful drugs, and you have to stay away from the belief that more is better. 1/8 of a Viagra makes your penis think that you're spending the day starring in porno movies.... that's more then enough for me! Also, with the lower doses, I've never experienced any side effects what-so-ever, so that's a bonus as well. Hope this helps any of you interested enough to try either of those medications!
