HIV can’t break through intact skin or mucosa. The virus can pass only through damaged skin or mucosa. Very small lesions are large enough to provide an opening for HIV-transmission. Minor lesions can be created during sex and such lesions represent open doors for the HIV virus and other sexually transmitted diseases. Condoms can prevent the virus from reaching those open doors, but not perfectly. Transmission of HIV from sperm or vaginal fluid to the receiving body via the skin or mucosal lesions should be very fast because HIV is very sensitive (weak) outside the body. The fastest transmission is a direct one that happens during unprotected sex.

In your case, it seems that direct transmission was prevented thanks to the condom you used. Indirect transmission could have been possible when and if your penis touched a clthing item made wet with vaginal fluids from the condom’s outer side. This possibility, however, is almost impossible. Nonetheless, you can ease your mind by taking an HIV test that can confirm or deny the presence of HIV antibodies in the blood.

Hypochondria is a kind of neurotic disorder wherein a person wrongly interprets the inner body sensations as a symptoms of a disease. It can be treated with psycho-therapy.
