There are two primary disorders that affect the male reproductive external organs: penis disorders and testicular disorders.

Sexually transmitted diseases (STDs) are diseases that are spread by having sex with someone who has an STD.

Sexual assault can be verbal, visual, or anything that forces a person to join in unwanted sexual contact or attention.

Sex is supposed to be pleasurable, but it's hard to feel intimate with your partner when you have sexual performance anxiety.

Paraphilias are problems with controlling impulses characterized by recurrent, intense sexual fantasies, urges, and behaviors.

Trichomoniasis is a sexually transmitted disease (STD) caused by a small organism called Trichomonas vaginalis.

Human papillomavirus or HPV is an easily transmitted virus that causes genital warts.

Don't try to treat a sexually transmitted disease yourself. These diseases are contagious and serious. You must see a doctor.

If caught early, syphilis may be cured with antibiotics. 

Gonorrhea causes no long-term problems if it is treated early in the course of the infection before any complications develop.

With treatment, chlamydia should clear up in about a week.
