How is it possible to become pregnant without inserting his penis?

yes if sperm gets on your vagina, it can swim inside it if he ejaculates puts pre-cum on your vagina, or inserts a finger or object in there with sperm on it, that can get you pregnant you can also get pregnant at any time of the month at any time you have sex so you could be pregnant, but its probably duw from stress however

to find out if your pregnant take a pregnancy test about 2 weeks after you had sex (any sooner and the results won’t be accurate) in the morning with your first pee is the best time and take it when your period is due alternatively, see a doctor for a blood test this will both let you find out quicker and give you more accurate results

and remember to LEARN about sex before you go off having it learn about as well as a male and female reproductive system birth control, contraception, pregnancy and sti/stds don’t have sex until you know the consequences involved with it because the main reason why kids and teens get pregnant and/or get stds is because of a lack of sex education
