I am 20 years old and in college. Today I took Adderall for the first time (un-prescribed) because a friend told me it would help me focus while taking an exam. The affects were great, I was able to focus really well. The only problem came later in the night when I was about to have sex with my girlfriend. No matter how hard I tried I just couldn't stay erect. I finally gave up after about two hours of fooling around. Now I am wondering what I'm sure anyone in my position would wonder, how long will this last and what should I do about the situation? Please help!!
P.S. My fingers are kind of numb (not sure if this has to do with the adderall or not)
Yes, i have experienced a similar side effect including decreased libido, too.
