I am 18 years old and I am having some difficulty with maintaining an erection hard enough to penetrate. I have had sex before but most of the time I either don't get hard enough to penetrate it, or it doesn't stay hard long enough. This has been happening for almost a year now and I really don't know what to do. I don't know how to tell my girlfriend this either and it is really hurting our relationship.
Are there any herbal supplements I could take that would help me down there?
I think you are very tense, if you get the stiffy bless in the morning, you have no organic problems. You are probably to tense, thinking if she will pregnant or not. also you need to be check for prostatism or infection in the prostate, but if you can get hard with your hand, or if you can masturbate without problems then is in your head you don't want to be a father not just yet. So you have to explain that to your girlfriend, or lover. If you think in other things while having sex you may loss the blessing too. Alos you thyroid needs to be check and you need to be tested to see if you are a diabetic or not. But is you can get stiff when you are by yourself and hold it for a long time, then is just your nerves while doing it with your girl. Godspeed
Performance anxiety wouldn't explain a lack of morning erections at your age or your sense that your erections while masturbating were not "full". There are a lot of possible causes for this but none that can be confirmed on a web forum. You really need to see a doctor about this. This could be nothing more than a symptom of a more dangerous condition.
You need your prostate check so when you go to your doctor probably he is going to do that. My advise let the doctor to check your prostate, he is going to do it thru you rectal area, and this is painful but they are trained to do it so is no going to be too bad. ALso if you watch a lot or porno you may be over stimulated, that means if you see a naked real girl maybe is not enough for you, you have to see more than that to get stimulated, so I advised to you to stop watching porno or porno pictures.
Yes, you should always feel free to bring up a question with your doctor regardless of the visit. It's very likely if he can't identify a clear cause that he'll refer you to a specialist and if you went to a urologist it could be difficult to explain it to your parents. You should look into getting yourself insured and taking on these expenses yourself.
