Qudos to you that your daughter can talk to you about contraception - so many feel thay can't - but knowing that you feel a bit sad about it maybe you can find out why she thinks she needs it and try to reassure her that a chap should love her even if she doesn't sleep with him (not that you haven't)? I know when I did youth work (back at Uni) I spent a lot of time with young girls, about 13-14, talking to them about this so I know how hard it can be, but I do think it's great that your daughter can tell you about this and not just talk to friends or young women at their youth club.

Best of luck to you
