Relationship labels

Ive been seeing this guy for about 4 months and at the start he said he wasn't looking for a serious relationship. We do everything a normal couple would. He introduces me as his girl to his friends but maybe thats just to let them know not to try anything. Im okay with what we have but i feel like a label would help make things easier because when ppl ask me about us idk what to say.

Has anyone experienced this?

What are your thoughts on the situation?

Should i ask him to clarify what this is or should i just assume?
