Relationships. Minor & an Adult

So this man just turned 23 years old & i just turned 17 couple months ago. This guy has been likeing me since last year (he didnt know my age) he thought i was atleast 18 because i do look much older  then my age & i am mature most of the time. He knows my age now. Hes always buying me things & picking me up and we're always hanging out. Hes told me many times he likes me & always flirts with me & compliments me. Do you guys think that would be weird if a 17 yr old went out with a 23 year old ?
