OK, so I am a healthy 20 year old and for the past year and a half or almost 2 years i have not been able to get a full erection without the help of some type of over the counter pill (viagra cialis livetra) now almost 2 years ago, i had full erections all the time. Morning afternoon and night. In the middle of class, in church. all the time. I masterbate normally i think for a 20 year old. no more than twice a day, and sometimes skipping 3 or 4 days at a time. I had sex with my partner wonderfully, with no problems. Now, I can get an erection with a pill but when i get the condom out it goes down, it seems without constant attention my penis doesnt react even with over the counter help. I cannot even arouse myself anymore. I dont know what to do. I have never heard of a 20 year old with ED problems, and i always thought it occured in older men. sometimes it feels like i should have an erection but its just as normal as it can be and none occurs. so i feel like im still sexually aroused but no erection is present. can that be a vascular problem? with the help of a pill i have an erection but not near the effect i used to have naturally. The penis is not as straight and has more of a bend. Not an upwards bend but downwards, so i feel that it is not Peyronies, I am a very active person, i was a 3 letter athlete in high school, and i continue to work out. I know i am in good shape and this just stumps me. Also i am not under any stress what so ever, and for it to last 2 years just seems like it would be more of a physical problem. I have a risk of heart disease in my family, and have been around smoking all my life. can this be a hardening of the arteries (Atherosclerosis) I know this can occur in the pelvic region. I also have a little burning sensation when i urinate but only after orgasm, it never happens any other time. PLEASE HELP IM REALLY WORRIED ABOUT MY HEALTH!
