as a med student i can give you a simple answer don't get it so deep you know ... but the gag reflex is not an easy thing to train ...
Don't think that deep throating is a necessity with oral sex. Most men can careless about that. But I think gagging depends on the size of your throat. Your throat may be too narrow so therefore you gag very easily.
Hi Tinkerbell, OK with lots of practis you can train yourself to take your mans p***s down your throat with out gagging, I have a great book and I cant put my hand on it, it covers foreplay and its an Ehglish book, and the other thing is if you can find some very old Forum magazine or there sex life letters books, these were the greatest books on homan relations ie sex,
I'm trying to think, I think I read that it you take a very big olive in your mouth and keep taking to the back of you throat, at first you will gag, but after sometime you will be able to take it right to the back with out gagging, something to try.
Good Luck
Put your hand around the shaft and keep your lips closed when going up and down so you don't go past your hand
If you really wanna go that far down just take it slow at first
