Abstract
Two experience check lists were designed for the current study: an initial questionnaire and a revised version for cross validation. The final questionnaire which contained 30 items for females and 31 for males was distributed to 199 males and 213 females. The items constituted a wide range of heterosexual experiences including petting, oral contacts, various intercourse positions and bondage. Coefficients of reproducibility were .88 for females and .85 for males. Ordering of items on the male and female scale were quite similar, as the rank order correlation of .82 illustrates. The most notable differences were the prior onset of female oral activity and the low ranking of both female masturbation and exposure to erotic materials.
