From past 2 to 3 weeks am unable to sleep and have heart palpitations when I try to sleep. But what I observed is I am not having early morning erection and I didn't find erection from past 2 weeks. I tested by watching porn and had erection but it was Hardly 60 to 70% of what I usually get and didn't last long and also I tested myself with reading sex stories (usually I get erection), but this time get erection for short duration and again didn't stay for long. Do I have erectile dysfunction because of sleeplessness. I am trying to sleep but my brain when it is calm it gives me a thought about ED and addition to that I get heart palpitations..these 2 things making me unable to sleep.upon that I am just 28 yrs old unmarried and ED problem is making my situation worse.
