Is that fucking right?
I would have thought that there were too few lesbian parents, compared with the number of traditional man/woman parents, to be able to conduct any worthwhile research into making valid comparisons.
So . . . fuck off!
Oh sorry, you can't can you.
Well, not without using a strap-a-dick-to-me or some other such implement. Either way it's a good excuse to show a picture of some lesbians ;-)
