Hey man I would just like to let you know I am having the exact same symptoms. However, I have yet to try propecia. So I am now thinking what I/we are experiencing is defiantly due to the rogaine.
My time line is different though. I was on rogaine for roughly 3 months before stopping 6 months ago due to lazyness. During those 3 months I did experience minor ED, it basically took much longer to achieve decent hardness but I never put the two together. But, everything went back to normal after I stopped using it. About 2 months ago I again started applying rogaine twice a day to my hairline and crown. And just like you for the week my labido was a monster, sex twice a day with the girlfiend along with major urges to masturbate had me thinking this stuff was f-ing amazing. (The rogaine was the only thing I had added to my life so it had to be the reason for the spike, my girlfriend isn't that attractive.) However after that first week everything came crashing down. Basically I can not get wood for the life of me. Forgive me for being graphic but If I masturbate long enough I can still ejaculate, but I never get hard. I have continued taking it for for roughly 3-4 weeks since the symptoms first arose, hoping that my body is just adjusting to the chemical. However that has not happened and I am becoming concerned.
I'm 27 and other then my narcissism associate with my hairloss I am in perfect health, I run, lift, nearly everyday I should not be having these problems. Tonight I am ceasing my rogaine use and if things don't get better in a week or two I'm going to go to a urologist.
One thing is interesting though. I wonder if experiences are tied to the fact we both started stopped and started using rogaine again.
Anyway please let me know what the urologist tells you/ or has told you about your condition.
