i am 18... wanted to be with a girl who was 15... it's really more of a be with her, not necessarily have sex with her. but i guess none of you understand that. a relationship doesnt have to include sex... one thing i find important is morals, and i beleive it to be of higher morals to wait till you are with the one you want forever to have sex...
but that's just me.
no, there is nothing wrong with 18 going out with 15, as long as your intentions are honest. i am 18, if i started going out with 15 year olds, i would definitely get to know the parents. i am not a dishonest person, and would prefer to have someone's trust in me...
now, to you fathers.
if a 18 year old man starts getting to know your 15 year old daughter.... assuming she's dating age in your mind, but he comes to dinner at your house, talks to you, always appears well dressed and respectable, and seems to genuinely be interested in being in the company of your daughter, not having sex with her... would you really be that hard about the relationship?
