Hey - so I've been dating this girl for two months now, for the first five weeks we were having sex two times a day, sometimes three, basically everything single day, and for me it was no problem - everything was fine and great...About a week ago we were having sex and randomly in the middle I lost my erection...Buzz killed the night and it has been happening every time we've been having sex since. I know this kindof thing is supposed to be linked to stress/anxiety and such but it is just so sudden, and when I start having sex with her I am completely in to it and don't see why after five weeks of solid great sex, I suddenly can't have sex once every two days without losing my erection...I'm worried that the initial problem (which I don't know what it is) will be replaced with a newfound anxiety for losing my erection which will become a new problem! Didn't think this sort of stuff was supposed to happen to a twenty-year old?

Any thoughts/solutions?
