Kinda related to some of the tips above, but something that reliably gets my partner off is when I relax and take his cock all the way down to the base so the tip is lodged as far down as possible. Then, I massage the head of it by raising and lowering my soft palate at the back of my throat (for those of you anatomical types). I've also found I can go for a long time like that without tiring out.

And as someone who has a hard time getting off through blowjobs, he can get there reliably 9 times out of 10 like that
