Does half penetration get you pregnant?

[firsttimegirl]

We're 23, and both no experience yet. We're just having this finger thing and a little bit of rubbing outside the girls opening,since then. But just noew,because im wet, my boyfriends half penis suddenly slip inside my vagina,it's not intentional. he didnt ejaculate yet when he suddenly inserted half of his penis inside me because we were just starting. Is this possible for me to get pregnant?hope not. what should i do to avoid this thing to happen? my first day previous menstruation was feb 22.

It's difficult to imagine how his penis could slip halfway into your vagina without intention, but be sure to use a condom or other birth control when such "accidents" are likely to happen.  You may be better off to avoid intercourse and use hand and oral techniques for a while.
