Because there are so many of these immune cells available where there is an infected STD site, the HI viruses have no difficulty entering the body. HIV is highly concentrated in the genital fluids, so a person with an HIV infection as well as an STD is much more likely to spread infection. People with STDs are also more vulnerable to HIV because they usually have sex with different partners. HIV infection makes treating and curing STDs take longer, and may also make the STD worse and more complicated to treat. The discharge is usually an abnormal colour white, yellow or greenish and there may be large amounts with pus that smell bad.
Men often complain of severe pain in the testis followed by swelling and tenderness in the scrotum.
Men often complain of a sore red foreskin and there may also be a yellow discharge under the foreskin. Sometimes the skin of the penis, scrotum and around the anus becomes red, sore and itchy. Symptoms may also include acute inflammation of the vulva and inner thighs, itchiness, painful urination or pain during sexual intercourse. The open lesions or sores are commonly found on the head and shaft of the penis in men, and on the labia, vulva, vaginal walls or cervix in women. Anal and rectal syphilis ulcers are frequently seen in homosexual men.
