Xenia, I'd go even further to say that the purpose and outcome of societal rules and traditions that restrict young women's sexuality (e.g. body covering, requirement of virginity for marriage, ostracising pregnant or sexually active girls - still practiced elsewhere, commonly practiced in the UK even 50 years back,) are just the same as sexualisation.
It's about conformity. It's about control. It's about maintaining collective male "ownership" of young women's bodies and how they use them.
With a burkha or a promise ring, the conformity and control is pretty obvious. What is devious, however, is that in our current "modern" society, there is just as much pressure for young women to conform to specific modes of dress, specific sexual practices that facilitate male control of women. What's more sinister though, is these are dressed up as "free choice" and even as "liberating" for the women involved. But, how much really is choice? What's worse, if you aren't "happy" with the outcome of your "choice," (e.g. sti, pregnancy, shame of nude photos of you splashed over the web, rape, etc.,) then it's tough, because after all, you CHOSE it.
Conformity and control with the illusion of choice is still conformity and control.
