Experimental sex research is an area currently experiencing it's re-birth in experimental psychology yet it is far from a new field. The Kama Sutra (कामसूत्र) was written over 4000 years ago and documents over 64 positions. If contemplating conducting sexuality research it is advisable not to have intercourse with your own participants, the practice is strongly discouraged by the BPS and the APA as it presents a legal grey area. One of the only sex researchers to successfully pilot a study 'Finding the G-Spot' (Oxenham, 2008) documented the ideal method of bringing the female form to orgasm. In the 2008 study, 99 females who had never before experienced orgasm through intercourse were brought to climax by the experimenter. This study also confirmed the existence of female ejaculation for the first time under experimental conditions, however only 28 of the 100 female participants managed to ejaculate. Critics have however suggested that these findings are not generalisable due to the extraordinary penis size, skill and agility of the researcher.
Human sex research is unforunately often blocked by ethical committees who fear emotional damage to participants aswel as damage to the reputation of their institution. Sex researchers therefore often uses cats and rabbits in order to test hypotheses without the risk of emotional damage to human participants. In a yet to be published paper, Fourchan et, al. (2010) tested his "Oral Copulation Hypothesis" by performing fellatio on rabbits. This practice has been strongly criticised by campaigners who blame animal sex researchers for transmitting the aids virus to the human species in the 1960's.
