All parents help me out! Awkward dilemma?

I'm glad that you are open parents and your daughters understand the basics of reproduction and , this can only be a good thing (as long as it's not too graphic) but at 7/9 I feel the explanation of may be taking it a bit too far. If she doesn't ask again then I would leave it be for now, if she does then tell a white lie.....tell her that they love one another and are able to be intimate in different ways than a man and a woman, basically make out that they DON'T have . I know it's a lie but going into the details of between two men is too much information for young girls, I'm presuming they only view as a way of reproduction at the moment so best to leave it that way for now until they're older, I'm no prude but I don't think it's appropriate.
