Texas does have a defense in such a situation. Here is the quote from the Penal Code
(1) the actor was not more than three years older than the victim and at the time of the offense:
(A) was not required under Chapter 62, Code of Criminal
Procedure, as added by Chapter 668, Acts of the 75th Legislature, Regular Session, 1997, to register for life as a sex offender; or
(B) was not a person who under Chapter 62 had a reportable conviction or adjudication for an offense under this section; and
(2) the victim was a child of 14 years of age or older.
Texas Penal Code, Section 22.011 - Sexual Assault
Here you do meet the conditions of the defense. As such you can be charged but you do have a defense. In addition I agree as to any charge for breaking and entering. Anyone who engages in sexual activity with someone under the age of consent (17) in Texas is liable for prosecution, including people only a few years older then their sexual partner and even two individuals who are both under the age of consent. But you do have a defense and because of that it is unlikely that you would be prosecuted even if you are charged and arrested. The only problem would be if the girl does not back up that the sex was consensual.
