Itchy skin rashes are very common in the genital region, which generally includes the area below the belly button to the top of the legs: the buttocks the area around the anus, and the vulvar, penile, and scrotal areas.
Many of these conditions on the genitals are sexually transmitted and uncommon in children or in those who are not sexually active. Conditions that may be sexually transmitted (but can also be acquired by other means) include viral infections such as molluscum contagiosum, warts (caused by the human papillomavirus), and genital herpes; infestation by insects such as pubic lice and scabies; and fungal infections, such as that from jock itch (tinea cruris).
Non-contagious conditions that affect the genital region include psoriasis, intertrigo (breakdown and irritation of the skin from moisture), allergic contact dermatitis, and irritant dermatitis, such as the condition diaper rash, which is common with infants.
