The hymen must break and the semen must get into the open vagina to make the lady pregnant. Even if it is the first time.
Usually the way you become pregnant is by having intercourse, but it is possible to become pregnant if a man ejaculated, leaving semen in the area outside of your vagina. If your next menstrual cycle is late you should take a pregnancy test.
To get a woman pregnant semen has to come in contact with the vagina. It is possible to ejaculate without an erection, did you ejaculate? And if so did the ejaculate come in contact with her vagina? Without an erection it would be difficult to deposit the semen deep within her vagina so it would be more difficult to get pregnant but I suppose if you ejaculated without an erection then took the ejaculate and pushed it into her vagina then it would be possible.

No, this is not possible. The only way one could be pregnant is if it was bred before you got it. They need to breed with the opposite sex to become pregnant.
