Anxiety based ED + Premature ejaculation

I have had a form of Social Anxiety Disorder since my teens.
Not surprisingly I really struggled with dating/relationships.
Eventually I lost my virginity but to my horror I had performance based anxiety ED which caused me to lose my erection during intercourse OR if I stayed hard for a short while I came withing seconds of penetration :(
Viagra had not yet been invented so I was put on injection therapy that involved injecting Prostaglandine into my penis with a tiny syringe OUCH! :(
This therapy is not talked about much these days but many years ago few options existed.
The injection had to go in one of two small areas in the side of the penis and about 50% of the time I missed the target area and nothing happened.
It was unwise to use the injection more than once a week so if I missed I could not try again.
THE GOOD NEWS.
I was hopeless with women frankly so I did not have an active sex life  but sometimes I got the needle in the right place and I had a raging hard on that stuck around for over an hour.
A side benefit of the therapy was I tended not to *** or at least not for a long time.
A few very special times I got to take my date not just over the moon but beyond.
I can't tell you what that did for my normally deflated ego :)
With this experience I knew with CONFIDENCE (a word unknown to me previously) that if I got the needle in the right place I could stop stressing and just focus on making my date happy knowing my penis would do his bit!
The trauma of the injections was extreme, it worried me greatly.
A medication called  Muse (a tiny solid pellet of Prostaglandine pushed up the urethra) promised an answer but it was VERY expensive and was reportedly ineffective because it could not be easily absorbed into the tissues of the penis.
I tried Viagra when it came along. I got an erection easier than normal but anxiety still caused deflation and I still came very quickly.
About this time (years ago) my shrink convinced me that it was futile for me to be dating and had me focussing on being "happily single".
I'm not a young person anymore and lack of sex is not as important to me now but for those of you who have similar problems I can't help but feel they had a great idea with Prostaglandine, pity they never figured out how to deliver it safely and efficiently because it was exactly what this anxious person needed.
