Relation without penetration or ejaculation can become pregnant?

I had a sexual intercourse, I did not penetrate and in fact, I just leaned against it, but I think I ejaculated, however I took it before something fell on it, but maybe something might have come in the way, is it likely that my girlfriend gets pregnant? Note: the relationship was standing.
Expert answer:

Relation without penetration or ejaculation inside or at the entrance of the vagina, do not get pregnant. However, if there was penetration, whether or not ejaculated, there is a risk of pregnancy.

This is because fluid that exits the penis during intercourse, before the man ejaculates, may contain spermatozoa. In this case, although the chances of getting pregnant are reduced, they do exist.

The call "coitus interrupted", which consists of removing the penis from the vagina shortly before ejaculating, is not considered a safe method of contraception.

The best way to avoid pregnancy is using a effective contraceptive method, like the condom or the contraceptive pill, for example. The advantage of a condom is that it also prevents sexually transmitted diseases.

Sexual relations without vaginal penetration is not capable of causing pregnancy. However, intercourse with vaginal penetration but without ejaculation in the vagina can cause pregnancy. If the couple does not want a pregnancy, it is important to use effective contraceptive methods.

Seek the general practitioner, family doctor or gynecologist to choose the best method.
