I like it when my girl gives oral and she says she likes to give it but, can't deepthroat my **** as she gags easily and nearly threw up one time, she says she wants to please me and deepthroat me but can't
She needs to relax first. Position can play an important key. Having her lay on the bed with her head hanging off the side and you standing on the floor in front of her can make entering her throat easier. Also, I find it a lot easier, depending on the shape and size of the penis to stradle him backwards, like 69, but sitting on his chest and do it that way.
She needs to take it slow.. doing it fast will trigger that gag reflex if she's not used to it. Tell her to take slow, deep breaths through her nose. Getting over the gag reflex is part mind over matter, and partly breathing correctly.
youre either born with one or not. you can train her to get more relaxed and better at it. throwing up may be part of it for her.
im lucky I don't have one. I love deep throating but it isn't as much a struggle for me because of my lack of gag reflex. I let one of my friends watch me on a dildo and she's like amazed and trying to get me to help her with it. lol
the guys I've been with have definitely been spoiled though. being able to have a guy literally "throat f***" you is something that he'll definitely never forget because not many girls can really do it.
