Welcome to the forum
Nope, each frog is going to be different some are more shy than other while some can be rather aggressive. It's normal for them to only snap at things right in front of them, they are very lazy. Nice frog, way too small to tell sex though. He probably is scared of you, make sure to move slow when feeding and what not, quick movements will scare him more, he will most likely associate you with food over time and be less fearful of you. He will never really "enjoy" your presence but he will tolerate you with time lol
