Taking Sildenafil Citrate to perform much better in bed

Taking Sildenafil Citrate or another name of Viagra, is quite a different experience for me. I don’t really suffer from impotency but I do have instances when my erection is just not hard enough and I notice that when I am fatigued from work or really really emotionally problematic. Sildenafil was actually being taken by a friend I had for the purpose of making his erection better and last longer so I thought maybe I could use it too for that purpose. I checked it out online in www.generic4u.com and I was glad I can order this without prescription and I took note of some other drugs that might be useful to try like tadalafil or Vardenafil. Whenever I am tired from work but I know I have an active night that same time, I will take usually in variation either of the pills I ordered to see a comparison, but you know what? They are all really effective that I cannot really say which is more effective and such, the important thing that matters to me is that I am able to perform well in bed and I can please my partner without having to suffer myself. I just hope I don’t really suffer erectile dysfunction in the near future as I have heard that my symptoms now are what precedes the real condition, but anyway I am glad that there are drugs like the ones mentioned above to help me in any case.
