I am 21 years. Last Day Me and my boyfriend were naked. He tried to enter his penis into my vagina. But couldn't enter since it was hurting me.
Can I have chances of getting pregnant?

Simple answer... yes its possible... if that's as far as it got.. then the odds are low... if he had a condom on those odds get lower.

If he didn't have a condom was you trying to get pregnant on your first time?

Simple answer....yes its possible....if thats as far as it got..then the odds are low....if he had a condom on those odds get lower.

If he didn't have a condom was you trying to get pregnant on your first time?
NO... he didn't have a condom... but his penis didn't enter fully... just a very small part entered for few seconds... Still do I have chances of being pregnant?

It doesn't matter how much he got in.. he touched it and that's enough for the possibility to be there.

So yes there is the possibility... but what the actual odds are is anyone's guess.

So.. you were actually trying to get pregnant on your first time? It appears to be the case.
