Hi Doc Can syphilis be transmitted if i swallow precum while giving a blow job?
Yes, but not from swallowing the pre-ejaculatory fluid. Syphilis is transmitted via skin-to-skin contact with an infected person. Someone who is infected can pass the bacteria from infected skin or mucous membranes (linings), usually your genital area, lips, mouth, or anus, to the mucous membranes or skin of your sexual partner.
The bacteria are fragile, so you cannot get syphilis from sharing food or utensils, or from using tubs, pools, or toilets.
