Yes, you can. Medicine is medicine, not a bullet. And, like all medicine, it must be prescribed by the doctor, as all medicine can bring unwanted effects. With Viagra (Sildenafil) and other drugs for erectile dysfunction – Levitra, Cialis and Vivanza – it is no different: headaches, facial flushing, nausea and visual changes are the most common effects. Secondly, the story that Viagra produces a super erection is a myth. The penis will not get bigger or generate incomparable pleasure. He will only have a complete erection similar to the one naturally produced by the body. It is true that the penis could recover for the “second half” faster. And also that any fears of failure would not hinder the erection so much. But there is a risk that the man will think that it only works with the medicine and that he will be able to have as many sexual relations as he wants, which is not true. Young men who have difficulty getting an erection may benefit more from practice, experience, and eventually therapy than medication.
1. When men get excited, their central nervous system releases nitric oxide (NO). NO helps make cyclic GMP (a messenger molecule) increase
2. Cyclic GMP makes the smooth muscles of the penis relaxed. The vessels dilate, allowing blood to enter the erectile bodies. It’s the erection
3. After some time, GMP begins to be destroyed by the enzyme phosphodiesterase 5 (PDE5). With that, the penis returns to normal
4. Medicines such as Viagra inhibit the production of PDE5, helping to maintain an erection
