You may be afflicted with Peyronie's disease. You are correct to be concerned, and that's why you should see a urologist for an evaluation and a proper diagnosis. Not much anyone can do over the internet. More info here: https://www.niddk.nih.gov/health-information/urologic-diseases/penile-curvature-peyronies-disease

Congenitally curved penis, either upward, downward or to the side, is not uncommon (1 in 5 males). This condition typically does not affect functionality and you should be fine if you have no pain with erection. You can visit a urologist for a complete reassurance.

This is called PEYRONIES disease due to scar tissue forming on the bottom of your penis. This is common in some men, some have a little pain, some don't. If the scar tissue is on top of the penis it would bend upward. No concern about having sex, just be normal and enjoy, but be safe.

Per the Cleveland Clinic, men with a ‘normal’ penile curvature report a curvature of the penis during erection that has been present since puberty or early adulthood. It differs from Peyronie’s disease in that there is no scar tissue within the penis, & the condition usually does not change over time. Like another doctor, I recommend seeing a urologist for a proper evaluation & diagnosis.
