"Stiff n Sore" emailed me to complain about a condition she calls "oral sex neck" that she suffers from when she gives her boyfriend head.
She says she gets a really bad neck pain that lasts for up to a day after the event.
Well, as with any sporting activity, (and giving blowjobs must surely be considered sport of some kind), if you’ve been pushing your body beyond its normal physical limits you WILL suffer from cramps and exhaustion.
HOWEVER... as with all great athletes, it's important to practice often and work through the pain barrier.
