Sex-Partner Roles in Homoerotic Relations: An Attempt of Classification.

The attempt is made to initially arrange in the terms of methodology the area of the research on partner roles in homoerotic relations. These issues have been noticed very early in human history (e.g., different roles performed or bimodal polarization), but only recently has science become interested in this subject. It is suggested to cover all such roles by the term sex-partner roles (SPR) instead of various other terms used and to classify them according to the ethological evolutionary approach into the appetitive and consummatory SPR. Further details of the division are discussed, and the utility of such classification is marked.
