My question involves criminal law for the state of: Texas

I am 18 and a senior and she is 16 and a junior our parents are both friends and are okay with us dating. However I am skeptical about it I know the age of consent is 17 in the state of Texas however I don't want to have sex with her just date her. I want to know what am I allowed to do before she turns 17. Can I hold her hand? Can I kiss her? what are my limitations.
