there are different ways of interpreting or defining "sex".. [align=center] - gender - physical and behavioral difference that distinguishes individual organisms according to their functions in the reproductive process [/align] -- @ : yes i think you can consider SOP or SOT as taking part in "sex" since "sex" is either physical or a behavioral trait. -- SOP is better because theres more of an interaction and minimal imagination..i dunno..when i hear a person moan..i get more into it.. hahaha -- with SOT you require a great deal of imagination since you dont hear the person enjoying what you were doing.. --i think people here in the philippines use SOT more..its coz its cheaper..specially with UNLITXT ahahahaha
