You should not be prejudiced or disadvantaged in any way, just because you are a woman ! I hate to see this, it makes me mad, but from what you have said, you have a good income, and a house, you should more than qualify as a sponsor, and its good to see sometimes its not always UK White boy, / Filipina relationships, so go for it and best of luck, it shouldnt be any different to the run of the mill visa applications, just follow the rules, and you will be fine.
Although it does seem that the embassy are just that little bit more protective of Female British citizens than they are of the guys, maybe its that nanny state interfering as usual.
They have in the past denied entry to Pinoy's coming to live with their UK female partners, who knows why, it does seem at times to be slanted slightly against, but in this day and age, it should not be, and you have to get on with it, and put all of these factors out of your mind, certainly if your husband/fiance was denied for any reason, I am sure on appeal, the Immigration judges would be looking very much in your favour, however, don't think about that just yet, just apply like everyone else, and best of luck with it.
