Well.. Before taking propecia I had really low libido, but that was because of "too much porn", I stopped it (yourbrainonporn.com), and I have to say it was the best thing that happened in my life... libido as if I had 16.. before that I used to buy 20mg Levitra and cut each pill to 5 or 6 pieces and with each piece I could maintain a really good relationship for 13 hours.. so well until I'm fixed I'll get on with that thing
