Actually, nobody is really sure why it’s called the “missionary” position. Cecil has some thoughts, but no conclusions. The obvious inference is that someone had inferred (with no evidence) that some christians had decided that the missionary position was the “correct” position. There seems to be little evidence that Christians have ever advocated such a belief.
Bonobos are not chimpanzees. There are a different species of animal. From your posted link:
kimera, no offense meant at all, but you made like 10 statements as though they were fact, so I’m just wondering how you know all this. not that any of it seems impossibly outlandish, but what’s the source? data, hearsay, experience?
And those extra three seconds make all the difference between a random, meaningless use of a subjugated female bonobo as a semen receptacle, and a warm, loving, union between two equal, caring souls. 
Gah. Hasty reading. Apologies. Please substitute “primate”.
Make her feel good without a penis? Huh? I’ve never heard of such a thing… 
I’m not the least bit qualified to answer the question. But I had an ex-girlfriend who left me for an older woman, and after we became friends again, she told me one day that her girlfriend had gone to the hospital that afternoon to treat a rib she’d cracked during sex.
I couldn’t ask, but my God I wondered.

All I can tell you is that there’s none of that silly air-tongue-kissing that you see in nearly every single lesbian porno ever made.
Asking how lesbians have sex is like asking how heterosexuals have sex. I’m not trying to demean the OP it’s just that there are so many ways to experience a sexual encounter I couldn’t possibly describe them all.
It depends on the individuals involved and the couple as a whole. Some like dildos and vibrators, some like any kind of penetration, some hate penetration. But yeah, I would have to say we tend to be more non-orgasm oriented during sex and take the sensations of the whole experience as a satisfying experience. There are times when it’s sweet, sensual, romantic and intimate and there are other times when you just f*ck each others brains out like wild animals.
But that’s all I’m going to say now because I just got an image of some skeeve printing out this forum thread, tucking it under his arm, grabbing the kleenex and heading off to the jerkatorium. :::::shudder:::::
Some of it is experience. I don’t want to go into details about my sex life without a thorough TMI warning, so I will just leave it at that.
I am studying Human Sexuality in school right now, so most of my information is from the texts I am reading. The bonobos information I got from Biological Exuberance by Bruce Bagemihl. The details about the most popular sexual positions comes from ‘Varieties of Coital Positions’ published in Medical Aspects of Human Sexuality by Langmyhr, 1976. Masters and Johnson were the ones who first noted the longer sex times in lesbian couples. I’m afraid I don’t remember which of their studies this was first noted, it’s just in my notes as part of a 1979 study. The oral sex information is from American Couples: Money, Work, Sex by Blumstein and Schwartz. The detail about sex toys was from my notes from class, and a site was not given for it. A google search on ‘Lesbian sex toys’ hasn’t been helpful in finding any cites for actual studies. 
squeegee, St Augustine, who was very influential on Christian sexuality said that the ‘missionary’ position was the natural one. Go Ask Alice is a great resource for individuals interesting in learning about different aspects of sexuality and the experts there contend that they really did try and teach others how to properly have sex. I will try and find some cites that deal with actual cases though.
I’m surprised nobody has tossed out this quote yet:
