Same as Trillian's DH, my DH said he didn't want to but we asked him anyway at the time, and still no.
Didn't bother me at all. DH is fairly squeamish and I was just so proud of how well he coped with all the blood/lochia - I'm glad he didn't faint
ETA: He can always decide at the time. I'd be surprised if the hospital staff didn't offer - it seems to be a common practice.
