Glad to help. Take care. EWH
Welcome to the Forum. There is no risk to you of acquiring any STD, including HIV from an exposure of this type. For starters, there is virtually no risk on getting any of the diseases mentioned from saliva. Furthermore, while in general there is virtually no risk of getting STDs or HIV through genital to hand to genital contact, in your case, even the theoretical risk is lower because of the time between her putting her finger in her vaginal and touching you. There would be no risk if she went immediately from her vaginal to your penis and even less (if such a thing is possible) in the situation you describe. In addition, that she placed her finger in her vagina several minutes before she touched you (including your penis) does not put you at risk. In the time between putting her finger in her vagina and touching you, any bacteria or viruses present would have died.
You have nothing to worry about and do not need testing. Take care. EWH
Thank you Doctor. I guess the herpe situation i mentioned has to be direct skin to skin contact with sore not salavia? I just get confused because some other websites say herpies can pass through salavia. Thanks for your rapid response. I don't think it possible to go faster from vaginal to penis like u said. lol. Thank you again.
