Does viagra (sildenafil) actually work to make your penis bigger? what are some pros and cons of it? would u suggest them to teenagers? where can you get them

Penis envy?: Yes, makes it 'bigger' when you take it, but not permanently. And frequent use won't do it either. It's not the kind of drug you want to get into the habit of using at your age unless you have a specific medical reason to use it, which I would doubt. Message to teenagers: FUGEDDABOUTIT! Not for recreational use! If you've got a problem in that area, see your doctor!!!
