Personally speaking, I date women in my personal life and I find dams erm... I'd probably get up and get dressed, but that's just me. That's from personal experience of giving and receiving oral from it. But everyone is different and it is a comfort thing, what I may say 'absolutely no chance' at may be just right for you. And no, I don't charge extra - what you see is what you pay. Like MM says, I get regularly checked (including throat swabs) so I don't worry about STDs and still have an active sex life with my other half.
I don't offer A-Levels, if you go anywhere near there I will react unpleasantly because you've just assumed I'll be okay with that. In my personal life I actually enjoy aspects of anal but that's with a partner I trust. I do offer OWO, but not CIM. Won't allow fingering, too personal; I do allow RO and 69. Toys on me won't happen in a million years - too personal.
Naturally I am quite dominant so I tend to attract clients who want to be submissive as that's a role I feel quite happy in - I offer mild Domination but I'd like to look more into harder Domme as I do have elements of it in my personal life. It is something I get asked about, I just don't want to use my own things on clients plus obviously male bodies are different to female bodies even beyond obvious things like CBT. I offer strap on, feminisation, cross dress, tie & tease, mild bondage etc. Personally I'd like a two bedroom apartment - one for a boudoir, one for a dungeon
just your average neighbour! Quiet girl. Never bothers anyone. Never plays loud music. Lovely woman.
Next door *thwack* "you have disappointed your Mistress!"
I would consider myself GFE though with a very strong lean towards Domination type services; I've always done what I feel comfortable with. If I tried to be, say, submissive, it wouldn't work - clients know what they're getting when they come to me. This has been longer than I meant it to be, but the chances are they're booking you because you - by existing - are not vanilla. You are the sexy woman in the photographs; the voice on a phone; you're already a fantasy in someone's head. People don't tend to fantasise about vanilla*, although for the client who wants you dangling from the ceiling whilst giving him a foot job and wearing PVC whilst humming Simon & Garfunkel, there are the clients who really do just want a bit of 'normal fun' (their words, not mine). Do what you feel comfortable with, because if you start doing things because you think you should, you run the risk of messing yourself up psychologically imo.
* some vanilla things are amazing though. Have you ever craved a McFlurry? Vanilla. There you go.
