I haven't done it with any of the three pregnancies...a mix of can't be bothered and can't reach, I think I have had a 7lb 13oz and a 9lb 5oz bub so far, and although I've had little internal tears and grazing, haven't torn the perenium as such. We tend to DTD right up to and beyond the due date, and fairly often and because my belly gets sooo big, it tends to be done....with me on all-fours....(trying to think of a polite way of putting it ) which puts a bit of pressure/stretch on that area anyway, so maybe that helps....your hubby might be awful pleased to hear that, too
