granted sex is an evolving characteristic in life, but where will it end? should it end? the first step for sex was for reproduction, the next would be desire to have sex, then the next step would be having sex for pleasure and fun, and then the next step would be pleasure and fun with a particular person

for people that are more "whores" and enjoy promiscuous sex, i don't think they have fully evolved in the sexual evolution cause they are stuck at pleasure and fun, and for those that do share intimacy with a particular person, but do so with means other than vaginal sex, and maybe a blow-job and licking some pussy every now and then, and perhaps even anal sex when the occasion calls for it, maybe even a little role playing, but for those that need leather and chains and role play excessively or have those weird fetishes for balloons or mascots or whatever, then they truly are not sharing sex with a "particular" person as much as they are having sex with a particular person as such and such........something that person must become, but truly is not......in this case, i think people that participate in these acts of sex are stuck on the evolutionary step of desire.....
