I was hoping to not have to ask my questions, but today I started to really worry. During the last week of December, I engaged in a "stupid" act with a married man. He been married now for 34 years. He performed oral sex on me and also licked my anus. He tried to insert his penis into my vagina, but I pulled away. I am sure there was precum as I saw and felt it when I stroked his penis. He did rub his penis against my vagina and anus. He also inserted his finger into my anus. I don't know if he had precum on his hand/finger. Before putting his finger inside my anus, he left the bed, went into the bathroom to put petroleum jelly on his finger. He then returned and we continued. I performed oral sex on him for less than 20 seconds. He did not ejaculate. In fact, his penis never actually became erect. When I asked him why he wasn't getting hard, he said it is because he is an old man (he's 58 years old; he is a big guy around 250-300 lbs and I believe he's on blood pressure meds, although I'm not 100% sure). Maybe I just didn't turn him on. Within the last week, I've started to get a persistent headache. Sometimes my head hurts and other times it hurts across the bridge of my nose and when I press my face. And now, today my ears hurt. I never had a fever and no muscle aches although my shoulders feel tired (I've felt that at other times long before December). I have had migraine's my since I was in my early teens and I'm now in my 50's). I've read the low risk for oral sex, but it's the finger penetration that is continually running through my mind. I'm afraid his precum got into my anus. Today I took a test for gonorrhea, chlamydia and syphilis and expect those results back by the end of the week. He said he does not have any sexually transmitted diseases, but I don't know for sure. I do know that he has had several partners over his life time. I know I need to take a HIV test, but I have to work myself up to that. How risky was this behavior? Thank you.
This was a no-risk situation. I would not be concerned.

Contributors: WWS initiated and coordinated the formulation of the study hypothesis, designed the protocol, and participated in data collection, interpretation of the findings, and writing of the paper; he is guarantor of the study. PvA had the original idea for the present study, and participated in formulation of the study hypothesis, data collection, interpretation of the findings, and writing of the paper. IS, together with her partner, participated in the first two experiments and helped design the protocol. EM participated in the execution of the study, particularly data collection and interpretation of the magnetic resonance findings.
To find out whether taking images of the male and female genitals during coitus is feasible and to find out whether former and current ideas about the anatomy during sexual intercourse and during female sexual arousal are based on assumptions or on facts.
University hospital in the Netherlands.
Magnetic resonance imaging was used to study the female sexual response and the male and female genitals during coitus. Thirteen experiments were performed with eight couples and three single women.
The images obtained showed that during intercourse in the “missionary position” the penis has the shape of a boomerang and 1/3 of its length consists of the root of the penis. During female sexual arousal without intercourse the uterus was raised and the anterior vaginal wall lengthened. The size of the uterus did not increase during sexual arousal.
Taking magnetic resonance images of the male and female genitals during coitus is feasible and contributes to understanding of anatomy.
“I expose to men the origin of their first, and perhaps second, reason for existing.” 1 Leonardo da Vinci (1452-1519) wrote these words above his drawing “The Copulation” in about 1493 (fig (fig1 1 ). 2 The Renaissance sketch shows a transparent view of the anatomy of sexual intercourse as envisaged by the anatomists of his time. The semen was supposed to come down from the brain through a channel which can be seen in the spine of the man. In the woman the right lactiferous duct is depicted as originating in the right female breast and ending in the genital area. Even a genius like Leonardo da Vinci distorted men's and women's bodies—as seen now—to fit the ideology of his time and to the notions of his colleagues, who he paid tribute to.

The first careful study—since the sketch by Leonardo da Vinci—of the interaction of male and female human genitals during coitus was published by Dickinson in 1933 (fig (fig2 2 ). 3 A glass test tube as big as a penis in erection inserted into the vagina of female subjects who were sexually aroused by clitoral stimulation (occasionally with a vibrator) guided him in constructing his pictorial supposition.

In the 1960s Masters and Johnson made their assessments with an artificial penis that could mechanically imitate natural coitus and by “direct observation”—the introduction of a speculum and bimanual palpation. 4 , 5 Their most remarkable observations regarding sexual arousal in the woman were the backwards and upwards movements of the anterior vaginal wall (vaginal tenting) and a 50-100% greater volume of the uterus. This increase disappeared 10-20 minutes after orgasm. When sexual excitement without orgasm occurred, the volume returned to normal in 30-60 minutes. Masters and Johnson presumed that the greater volume of the uterus was due to engorgement with blood. However, they qualified their presumption: “In view of the artificial nature of the equipment, legitimate issue may be raised with the integrity of observed reaction patterns.” 4
In 1992 Riley et al published an ultrasound study on copulation. 6 The images were of relatively poor quality as they used hand held, self scanning equipment, and none of the images was overview. We used magnetic resonance imaging to study the anatomy and physiology of human sexual intercourse. Our search started in 1991 when one of us (PvA) saw a black and white slide of a midsagittal magnetic resonance image of the mouth and throat of a professional singer who was singing “aaa.” He remembered Leonardo's drawing and wondered whether it would be possible to take such an image of human coitus. We decided to try, as an ad hoc “instrument-oriented” study, despite the unscientific and other irrelevant reactions we expected and received: honi soit, qui mal y pense.
Magnetic resonance imaging had already been used as a diagnostic tool to study erectile impotence 7 ; it is particularly attractive for this kind of study because it produces images with exquisite anatomical detail that are clearer than those obtained with ultrasonography or radiography, and—as far as we know—it is safe. The aim of the study was initially to find out whether taking images of the male and female genitals during coitus is feasible, and later whether former and current ideas about the anatomy during sexual intercourse and during female sexual arousal are based on assumptions or on facts.
The participants (pairs of men and women) were recruited by personal invitation and through a local scientific television programme. Respondents were invited to participate if they met the followin
