If a guy is 18 and having sex with a 16 yeard old and she gets pregnet, does he go straight to jail? If yes what can he do to prevent jail meaning marriage or other acts?

This is not a question we could answer with any certainty. Some do spend time in jail, some do not. It depends on the circumstances of the case, past history, etc... Only an attorney could advise him on preventative measures.
