Oral Sex

I don't understand why some women have a problem with this. Women always want men to go down on them, but, if you suggest it to them they either don't do that or you get "its disgusting"!!!! Then there's the part after you get married. How come some women would do it alot before they got married but after they get married it STOPS!!!!! And don't get me started on swallowing. Does anyone else have this problem?????

Thanks,
