Can precum out side of vagina on ovilations days get a girl pragnent even if penis touched vagina for only few 20 30 secs. really confused by the answer online need a proper answer plz help?

Need to use safe sex: Semen deposited at introitus or in vagina can potentially lead to pregnancy regardless of amount of time. However, it is much more like if penis is inserted into vagina.

Yes: Any time a naked penis touches a naked vulva (vagina, labia, clitoris, etc.), there is a chance for pregnancy to occur. There is also a chance for sexually transmitted diseases to be spread as well. Using condoms will help to decrease both of these risks.
