NSFW Is it woman's obligation to modify or diminish her sexuality in order to better conform to society and prevent her own victimization?

I was talking to a friend the other night. I explained to him that I imposed rules on myself following a rape involving everything from the way I behaved, dressed, limitation of partners etc.

That actually this was not in reaction to the rape but to people’s perception and treatment of me.

There was in fact no evidence that the rape occured because of any in/action of my own. Regardless, the overall consensus that my behavoir warrented it. When I went to group they focused on rape prevention. Involving everything from the way women dress, to how we act in public, identifying potentially dangerous situations etc etc.

I had some some what unconvential views on sex and relationships. Admittedly but I was honest about my intentions.

For the first time since I felt shame and guilt for the rape and grudgingly accepted the measures I am questioning:
A Whether they do any good or are proven effective.
B Whether or not the all that was accomplished was compromising my beliefs and self in the face of fear?
C Whether these preventative measures have more to do with maintaining the status moral quo of our culture then they do self protection?
D. Do they in fact stigmatize women, I mean in practice the position they adopt is there is no shame or guilt for rape survivors. But at the same time they teach you how to prevent becoming a victim again. So which is it.

This contradiction even so many years later has left me struggling with my own responsibilty and when I can let go and let loose. The rape itself matters little to me other then being the cause that lead to this effect. So please be as honest as possible.
