Hey recently I had sex with a prostitute even used condom as preventive measure but the condom broke down in the vagina and my penis was directly contact with her vagina for 3-5 seconds and then continued with a new one, I just wanna know what are the chances of being infecting with HIV or other STPs if she may be HIV positive. Pls consult me on this I am really upset from this and do tell me do I need to be tested.
