I have noticed that my erections when i am aroused they dont stand robust but they are throbbing or pulsating. the penis is like moving. dont know how to describe it. Does somebody know why this is so.
thanks

I really don't understand the question.

I don't know the science behind it, but I can tell you this is very common and not an indication of any problem. Your erection quality is normal, if not better than average.
