(19m) Penile retraction due to anxiety

For some reason my penis is always retracted. For most of the day unless I’m in a hot shower or completely relaxed. It’s extremely uncomfortable and it causes it to poke out of my pants because the skins gets very tight not only on the penis but also the scrotum. It happens a lot when about to have sex too. It’s extremely depressing. I don’t know if it’s due to blood pressure or anxiety or something else. Even if I’m horny it doesn’t get hard with a girl because it’s retracted. When completely relaxed I’m around 7 - 8 inches and when it’s retracted which is most of the time it goes below average if I can even get it somewhat erect. I don’t know how to fix this. I tried relaxing the area with Botox but it’s too costly and it wares off in a few months l.
