Can a 13 year old female get pregnant?
yes. A girl that is able to have a menstrual cycle, is capable of getting pregnant through sexual intercourse.
If the 14 year old (male) is producing sperm and if the female is having monthly period then the female is able to produce a child. (If they can bleed then they can breed). The answer to year question is yes. I would recommend protection between the both of you, since neither of your are the age of having sexually activity.
Can a 16 year old male get in trouble in the state of Texas for gettin a 13 year old female pregnant?
12-13 year old girls should not be having sex and YES you CAN get pregnant if you are ovulating (having your period) 12-13 year old boys can also get them pregnant. Boys can begin ejaculating as early as 10 years old. There could be 10 yr old boys producing sperm. This is not often, but certainly possible.
