I am an 18 year old male who has a problem. Ever since 2 years ago I bave been having problems getting erections. I was at a party and it was around three o'clock in the morning and I was sleeping and a girl grabbed me and wanted to have sex with me. I was a virgin at the time so i was very nervous and have been drinking a lot. It turned out that I couldn't get erect and ever since then been having problems achieving an errection. My present girlfriend who I have been with for over a year and a half has also seen this side but has been very helpful with me and keeps on telling me that it is a mental thing. I read on your website about masturbation at an early age which I started around eleven and done it three to four times a day. I've learned that I have to cut back on that. Recently when we have been having sex, I do not have a full erection and from this I ejaculate very prematurely. I have a slight confidence problem especially since my penus is not all that big in the width sense. So if you could help me out with my size, stamina, and erection it would be greatly appreciated. Why is this stuff happening to me I'm only 18 and should be at the peak of my sex life. Thanks
