I think I'd categorise vanilla as vagina in penis sex (yup, straight only) with no role-playing or fetish-exercising of any sort. At least that's what I was thinking of as I read that piece. Oh, and no toys. Oral is foreplay, never the main event.
I don't really think most people have (only) vanilla sex.
No, I don't either, esp. when using your definition.
PIV.
My OB/GYN was unfamiliar with this term when I used it with her. I'm glad to have educated her, but -- really? She's been practicing for at least 18 years, since I've been seeing her since I was out of college. No one has used this term?
vagina in penis sex
For some reason this makes me think of Klein bottles.
I love you people madly.
"When I have sex with lesbians, hey want me to self-define as a lesbian. When I have sex with bisexuals they want me to self-define as bisexual. When I have sex with straight men they want me to self-define as straight. I don't like boxes. I define my sexuality as 'curious'."
I think I've said this before, and I apologize if I'm repeating myself. The term "heteroflexible" unfortunately gets used a lot to mean "Tee hee, I'm a woman who makes out with other women in bars because the men think it's hot!" But that's really the only term that I can apply to myself. I'm honestly not bisexual. And I can't say I'm straight, because my boyfriend is also quite literally my girlfriend (because gender has nothing to do with genitals, which is a discussion I'm happy to have, but not at this exact moment, b/c I have to jump in the shower). With a trans* partner, to call myself straight is both inaccurate and also erases his trans* identity. So -- heteroflexible. But I don't make out with other women because the men think it's hot.
(I will, however, make out with other women if *I* think *they're* hot. It doesn't happen often, though, because -- monogamous. Tim is fine with me kissing women, but not men, as long as he knows about it first. I am fine with Tim kissing men, but not women, as long as I get to watch. Because I am a voyeur like that.)
t edit And let me tell you -- digression -- the monogamy KILLS me some times. I've met only a couple people who have made me very seriously consider a poly lifestyle. But, in the end, I know I am not built for polyamory. I'm unbelievably jealous and possessive, and I don't manage my time well (which is not meant to be funny; sometimes I think the hardest thing about being poly is managing one's time so as to have adequate time for all partners). Fortunately, I am exceedingly, X-ratedly happy with my monogamous partner.
