Blowjobs are just kind of okay. I agree on the fact that they're often/always bite-y if they're trying to get more than a third into their mouth. I've had exactly two orgasms from blowjobs in 30-odd years of experience. I got very, very close a third time.

On the other hand, tying your partner up and face-fucking them while they choke and gag is pretty goddamn amazing, even with teeth. (Yeah, I'm a little sadistic; thankfully my partners after my ex-wife, including current, have been at least a little masochistic.) Pro-tip: quit before they vomit, both because that's unpleasant, and also because they usually want to stop after that point. I haven't orgasmed that way, but oh my god, so worth it.
