I'm sorry! That doctor sounds horrible.
Most of my babies have been "macrosomic," and I've never had any tear that needed suturing. Also never did perineal massage.
I also don't know that I've ever heard of a head getting stuck halfway out, although shoulder dystocia (stuck shoulder) might be a possibility, most good midwives know plenty of "tricks" for getting a baby unstuck (usually position changes, sometimes also helping free the stuck shoulder).
