My friend made love with CSW , oral with condom , enter the vagina with condom. During the process , change condom one time, may be little secretion touch his penis. He confirm the condoms is ok, his penis hasn’t any fresh wound. I told him it is safe, without any risk of STD and HIV , don’t need be tested. He is still afraid of STD and HIV. Please give him some suggestion. Thank you very much.
