My name is Ben, I'm 18 years old and I have been experiencing erection problems, I know I shouldn't be at this age but for some reason it is a persistent problem. I have had sex countles times but when ever I find a new partner, I seem to not be able to get an erection. The only way for me to have intercourse is if she stimulates me beforehand. This sucks as you could imagine. What are some key things to help me get errect cause I am desperate. Thank you.
