If the idea of blowjobs or taking some nice warm cum on your face offends you, this is not for you. For me blowjobs are a beautiful thing. Slow, romantic, rough, submissive, dominant - there's so much to blowjobs it'll be impossible to write everything down in one go - so this is about the rough type. Girls, you'll need to be submissive to enjoy this fun.
This isn't about you teasing him, you being in charge or anything of the sort. This is about him grabbing your head and ramming his cock repeatedly down your throat while you gag and splutter on it.
First: all women can deepthroat. Men love it so learn to do it. It's just not fair to keep it from him just because you gag a little, the look of pleasure on a man's face, his eyes rolling back as your lips reach the bottom of his shaft is worth it and if you can do it no man will leave you (unless he's a complete idiot). Sorry if this sounds sexist but it really isn't that hard a thing to learn to do (and you'll probably get jewellery more often).
This is where being close helps, the only way you're going to be get used to having cock down your throat is to take cock down your throat. People say use frozen bananas but having something cold down my throat just sounds painful.
