These might include the lack of ability to get and maintain an erection firm and long enough for sex (erectile dysfunction) or, uncommonly, a persistent and usually painful erection that isn’t caused by sexual gratification or arousal (priapism).
Other typical concerns might include the inability to ejaculate, premature ejaculation, delayed ejaculation, painful ejaculation and retrograde ejaculation (when semen enters the bladder instead of emerging through the penis).
If you have a persistent problem with ejaculation, visit your doctor, who will examine you and discuss the problem with you, or refer you to a specialist.
Sexually Transmitted Infections (STIs)
Most STIs show obvious symptoms, but some are not so easy to spot. If you are sexually active, get regular checkups and make sure you know what STIs look like when they do indeed show up.
Various sexually transmitted infections can affect the penis, including genital warts, gonorrhea, chlamydia, syphilis, and genital herpes.
Common signs and symptoms might include painful urination, penis discharge, and sores or blisters on the penis or in the genital area.
A condition known as “phimosis” occurs when the foreskin on an uncircumcised penis can’t be retracted from the penis head.
“Paraphimosis” occurs when the foreskin can’t be returned to its normal position after being retracted.
Other Diseases and Infections
A yeast infection can cause a reddish rash and white patches on the penis.
Inflammation of the head of the penis (balanitis) might cause pain and a foul discharge.
Peyronie’s disease, a chronic condition that involves the development of abnormal scar tissue in tissues inside the penis, might result in bent or painful erections.
