Give him a chance if you are interested in him.
He might change his mind later and want something long term with you.
Either way, if it doesn't work out its not like you have to be with him.
Its actually normal for most people first relationship to last only a month or few.
You're right that experience in dating is important, but don't date him just for experience, do it if you want to actually be with him.
The fear of getting too attached is normal but a risk you must be willingto take if you want to enter a relationship with someone
I became more attached to both of my first two girlfriends than they were to me so I was hurt both times when they broke up with me, but f*ck it it was somethin to do.
If you don't want to date him, then don't.
