During sex with a unknown female, I used plain condom but while doing it, I removed it and changed to another one with dotted. My fear is since some of her vaginal fluid must be on my hands (fingering) and with same hands I changed condom by touching my penis, is it possible to catch HIV virus? Both condoms were intact after sex (checked myself). Please guide me. My only concern is touching of vaginal fluids on my hands to my penis.
