Gagging and forced deep-throating is getting really, really common in hetero porn. I find that more of a turn-off than 2 Girls 1 Cup, to be honest. One I can completely disassociate from and look at it more or less objectively (it's peanut butter and chocolate pudding!), the other just makes me cringe and gag sympathetically.
If you can deep-throat with ease and/or practice, all the more power to you. The thought of someone grabbing my ears and forcibly jamming their wang past my tonsils makes me gag.
