Yes, it is possible if you have no gag reflex. Yes, you do choke but if you deepthroat like that is usually because you kinda like choking. No, breathing through your nose is almost impossible in this situation, but there are people who are able to. No, usually dicks are not this big (sad-small-dicked men everywhere sigh) so they don't reach this far in your throat

Lol, well given that there is always a minimal risk associated with oral sex the answer is condoms or PrEP besides the usual aspects of common hygiene and avoiding promiscuity (same sexual partner). Given the rough nature of the practice and the eventual microlesions assiociated with it, it is still a bet though. Hence the questionable "safe". :P

It is slightly different. The vagina is elastic and uses this property to accomodate the penis. The throat not as much given that its mainly function is to swallow. In the first case both the man and the woman lubricate their own sexual organs. On the second case you should know already in the mouth there is only saliva which can hardly act as a lubricant (forget if you have seen somebody spitting on you know what it just doesn't work like that :P ).
Okay.. some one please enlighten me, is that possible, that deep throating thing and how did he not choke. That looks dangerous. And that thing went deep in his mouth, food pipe.
