I certainly know of one but I am not comfortable enough with you to provide her name.  Suggest you look at some reviews.

The gagging was something many guys like. I can get a big one down, but not without some gagging, choking and a whole lot of spit.

I mean if a girl can take a guy all the way and not gag, he might think he isn't that big. LOL

Just an observation.

I have been looking at review and not many people talk about DT or gagging that much.  it's not like I can select it on search criteria.  now that would obviously make it easier.  but if your not comfortable then that is fine.
