Though there are some exceptions, the age of consent is 17 in Texas. That means that an older person can lawfully engage in consensual sex with someone who is 17 years or older. Texas law explicitly forbids any person from engaging in sexual activity with a person under the age of 13.

Can a 17 year old date a 14 year old Texas?

17: It is legal for a person to have sex with someone who is under the age of consent so long as both parties are at least 14 years old and under 21 years old.
