i don`t like the taste of it too, but i have never puked from it. well i usually don`t bother swallowing, but it is not that bad...maybe i haven`t been with a guy that sperm is so nasty. thank G O D for that!
Obviously, you belong in a convent. The ways of the gods are mysterious. "Get thee to a nunnery!" (Shakespeare)
Just swallow as it spurts with is penis abut 1/2 way in your mouth. Try that, but it really sounds like you have developed a mental block. If posible, try to get over it, you both will be much happier in the long run.
