Is it Okay ? or no ?

So ive know this guy for The longest time like since I was  in 8th grade and we have always been really close and we both like each other but I'm not really sure what is keeping us apart but anyways during all these years he always told me he wanted to have a sex with me but that he understands if I don't want to lose my "V card" and just some days ago I finally gave it up to hi and I todo my friend about it and she said it was really bad cause of are age difference what do y'all think I'm 16 and he is 19 (we live in the state of NM)
