I read and understand your concern. I am Chat Doctor answering your concern. You are not infected with any STDs including HIV. Please allay fear for the same. As you have not penetrated there is no question of HIV infection. Secondly rubbing genitals can cause STDs but only itching and tingling cant be STDs. STDs usually present with some other sign and symptoms apart from tingling and numbness. Usually it is present with discharge, swelling, redness etc. As you have taken the antibiotics there is no question left for any STDs. Your problem may be wanes of in some times. Please maintain good hygiene by cleanliness over the penile area. Avoid sexual intercourse during this period, or you can use condom instead. I will be happy to answer your further concern on bit.ly/ Chat Doctor. Thank you, ChatDoctorInfectious diseases specialist, ChatDoctor </s>
