There was a case where a rapist managed to escape conviction be cause he did stop to put on a condom. If I remember correctly, he made his victim put it on him (or, it might have been that she begged that he use one, he agreed...). The courts ruled that this made her a willing participant.

I have not yet followed the link so I am not sure if it would also limit the use of other barrier methods such a the female condom and diaphram.
