Swallowing helps. It ADDS to the experience for the men. Not sayng that it's not enjoyable without it, but I do think that it detracts form it if you turn to spit it out.
I would say this, if the taste is the problem, then swallowing would help you to AVOID tasting it. Spitting it out will actually increase the contact with your taste buds. If you let it NOT touch your tongue, you will not taste it.
I love to perform oral on my wife, and she can get really wet, and my face is literally covered by the time I am done. SO us guys are getting PLENTY of your fluids. I have not gotten her to kiss me afterwards, which I would love. She sees tasting herself as somehow being GAY? Seems stange to me, but I don't push it.
