I doubt very sincerely that it is due to your personal beliefs, unless you wear a baphomet or inverted pentagram on a first date...
My fiancée is what I would call 'on the fence.' She appreciates what I believe, and agrees with me, but sees no need to affiliate herself at this time. Does that mean she isn't a Satanist? No, she just doesn't take on a moniker for herself, which is fine. Does it mean she would never join the CoS? No, but being that it is such a personal decision, I would never try to coax her into it. Though admittedly I've told her how cute one of the HKP bombshell pink medallions would look on her...

To think that you will only date or be with a Satanist is fairly close-minded. While it may not behoove you to date a radical xtian, I think you'll be lonely (and may pass up a good thing, even if temporary) if you attempt to be so selective in regards to beliefs. There aren't that many Satanists out there when you compare how many are registered to other faith in the population (this would exclude defacto Satanists).
I think that if you were in fact a truly 'Satanic Woman' your trials would be much more fruitful. Read the Satanic Witch, and start reaping the benefits. If you had to 'dumb it down' to get what you want, that doesn't make you less intelligent. It would actually show you to be even more so.
