Deciding back to Buy Sildenafil rather than Tadalafil

I though long and hard before I finally decided to go back and buy Buy Sildenafil instead of some newer drug like Vardenafil and Tadalafil. This trouble all started when I was complaining to my friend about my problem in erectile dysfunction and told him I was actually taking Viagra or otherwise known too as Sildenafil Citrate and we started to argue because he ueed to Buy Tadalafil himself and we were countering each other on which we think was more effective and more useful to men around the world. Of course though we countered each other, I also was considering some of the things he said about Tadalafil which sounded good like having harder erections or longer lasting things. I countered that Viagra was the first to come out and was more widely accepted and that it was situational for every person. But at the end of the day, I was also considering to try Tadalafil out of curiosity. I went online to www.generic4u.com where I always buy my drugs and there looked at both drugs thinking quite hard if i should also order The other one as an experiment. In the end, I decided to stay back with my Viagra as I really prefer my comfort with this drug and up until the time it wont work anymore for me, then that is the time I will buy some other drugs like Tadalafil and see if this will also work for me like Viagra did.
