Is it too soon????

So I’ve been talking to this guy for about 3 weeks now and everything is going great - I’m 100% comfortable talking to him and we both know the kinda direction it is going but when would it be classed as too soon to start dating? I’m not overly experienced and don’t want to rush into anything so I’m unsure of when to expect the question - when do you think it would be acceptable to start dating?
