Evolutional background of dominance/submissivity in sex and bondage: the two strategies?
The preference for sexual arousal by dominance and submission may be connected to strategy respecting rank, while the preference for "bondage" may be derived from an opportunistic strategy that may be essential for possible partner problems solution. From the evolutionary biology point of view, these patterns of sadomasochistic sex appear as adaptive rather than as pathology.
Our results add new information about the control of endothelial function elicited by monomeric adiponectin, which would be achieved by modulation of NO release and Ca(2+) transients. A signalling related to Akt, ERK1/2 and p38MAPK downstream AdipoR1 would be involved.
