throbbing cock ,full length
I was wondering that when Iam having sex my dick to stay hard ,it starts to throb or pulsate causing my girlfriend to get even more exited and wet. When Iam sleeping in the morning ,my girlfriend tells me that I have the biggest wood and it throbs every few seconds and it stays like that for a while.
Well I want to ask if there is any exercise or routine done specifically to achive and maintain a hard pulsating cock , So when having sex all your inches are felt inside her. Because if not , then whats the use of a big tool?
I dont think Iam looking for Kegels as the answer.
thanks for the help
