Totally agree - there's no risk here.
When we talk about oral sex, we are talking about the penis being in someone's mouth, or putting someone's mouth on a vagina, for a period of time long enough to transfer any germs.
A quick kiss to the genitals, either a penis or vagina, isn't going to do that.
Hand jobs never transmit STDs.
Hi, what your describing would be zero risk to contract any std. Oral sex can pass things like syphilis and herpes but a they need to be massaged into the skin to be contracted. A simple quick kiss would not be something to be concerned about.
