23 year old with ED. Looking for some help

[help304]

I'm a 23 year old male who has always seemed to have issues with getting and staying hard. Even when masturbating in my young teens I didn't get great erections. At 16 I attempted to have sex and had an erection and felt ready to go and lost it. I have tried on other occasions and have the same thing happen. I would always think I could not maintain erections because I was obese and had high blood pressure and took lisinopril. I am now at a healthy weight and do not take any blood pressure meds. Sometimes I am able to maintain a weak erection while the girl is on top but when I try to switch positions, the erection is gone. I have been too uncomfortable to talk with my doctor about the issue but I know that it's time. About a year ago I purchased Viagra online from out of the country. The Viagra worked wonders. I have been taking 50mg about 30 minutes prior to sex and I have great erections. With that being said, I would rather not have to take Viagra if there is an alternative. This issue has killed my self esteem and confidence. I don't know if this is all just performance anxiety or something else or a mixture. I do wake up with good morning erections on occasion.
Thank you to those who took the time to read this. I have never posted in a forum before. I hope you will share your thoughts on my situation.

HPB interferes with erections, it is known to cause erectile dysfunction.
when i was a teen, before is started mbing at 17, i also had rock hard erections, randomly, when stimulated visually or by my pants.

Thanks for the advice. I went to a urologist yesterday and he took some blood and urine tests. He basically said that it's either a metabolic issue (possibly low testosterone) or it's anxiety based. He had no hesitation in writing an Rx for Viagra but I stressed that I don't want to take it if there is another option. Hopefully the lab work will provide some answers.

You may Google Male Deer exercise, kegel exercise and Sat kriya. Regular work out can regenerate your sexual strength. Do not masturbate with dry hand and do not stop breathing while masturbating.
