If you don't desire that sort of protection or aid, at least insist that the two of you begin to meet with others who know one or both of you well so that there will be consistent accountability and an outside perspective on how the relationship is going.
Humble openness to accountability is essential to a godly relationship. It's not exhaustive coverage, I realize, but this should at least get your relationship started on broad principles.
As I've written on this site before, "practice" and "recreation" are not good reasons to date.
Dating is for the purpose of finding a marriage partner.
As I mentioned, he should not do this until he is "ready" to marry.
