The other night, I had a one night stand with someone and it's been 3 days since that encounter. I do not know if she has any std's or anything about her past sexual history. During our encounter, there were times when I used my hands to rub her vagina, inside and outside, and had her fluids on my fingers and hands. The problem is, when I ejaculated, I pulled off the condom and masturbated using the same hand that I had her vaginal fluids/secretions on. Is it possible to contract any type of std this way? Also, there were times where she herself had rubbed her vagina, and used the same hand to rub my penis to get me erect before I put the condom on. Could this be a possible way to contract any type of std, such as herpes, or any other kind? I'm worried about contracting an std such as herpes, if she had it, since condoms only cover the shaft and head of the penis, and not the base of the penis where it can still be in contact their vaginal fluids/secretions. And if the vaginal secretions can somehow get inside the condom through the base, wouldn't that make it highly possible to get an std?
I've read that genital to genital contact is necessary for you to contract stds, but I do not know whether or not you contract stds if you have their secretions on your genitals by hand to genital contact. Is my situation something that warrants an immediate std testing? How long should I wait to get tested or am I just being paranoid about the whole situation??
