age difference

Do you think a 18 year old dating a 33 year old is weird, if mu mom is okay with us talking yes im about to be legal but do you guys think a 15 year age gap is fine if they both are willing to commit to this relationship or is it weird...??? I've know him for about two years and he doesn't want to do anything till I'm 18 he has dated girls his age and we do have about the same maturity level he doesn't act 33 he still has a childish side and it's cute and he funny and he cares...And I want to know what people would think about this relationship!? And we know people these days are judgemental and we are ready to deal with that but I want opinions on this... So please comment..
