how do you make your parents accept your b/f?

ok, i have a problem, my b/f is 20 and i'm 15, we barely started going out, and i've never felt like this with anybody else, were taking it slow, and he respects me and is not too mature for me, beacuse i'm really mature for my age, so we don't have a problem with the age difference or nothing like that. the problem is . . . . . my parents, they're kind of strict and i don't know what they'll say when they find out he's 5 years older than me, i really like him a lot and we really both want to be together, but i don't know how my parents are going to take it, he doesn't want to lie about it because if they ever did find out it would be worse, so does anybody have a good way of telling my parents about it but not so that they will be pissed of at me, but will be able to understand?

im in the same situation and even worse he is in jail.....i told them just straight forward the truth about everything tell them that they can be angry with your relationship but you want to be with him and if they are scared he is going to hurt you tell them you want to learn from yout mistakes that htey cant protect you from pain it happens in everyones life...but your happy for now and they should be happy for you

thanks kami for your help, this is one of the hardest things i'm dealing with right now, so your advice helps, and i hope that it goes good with you and your b/f too,

come on people, any more suggestions? I really need help with this!!!!
