I don’t think most virgin martyrs are celebrated for resisting rape. These stories follow a pattern.
1)Most of the time, these old hagiographies have something like an arranged marriage set up, with the girl refusing because she has decided on perpetual virginity for religious reasons.
2) Almost always, this outs the girl publicly as a Christian, which is already illegal.
3)It then escalates into the girl’s family, or the man, trying to get her to abjure Christianity, which they see as the obstacle to the marriage, and as a crime in and of itself anyway.
4) She refuses to recant her faith.
5) They kill her because of all of the above.
As far as men dying in similar circumstances, yeah, the Ugandan martyrs died because they did not want same sexed copulation with the king after their conversion.
I am going to qualify Augustinian’s statement, and say that the primary reason for their execution was a refusal to have sexual relations any more (why didn’t he kill chiefs or women who converted in his court?) though, not the sole reason.
Most were certainly not virgins. I might be surprised if any were. But that’s not the point. If they died for sexual dignity and chastity, then it is even more inspiring if they weren’t virgins isn’t it? That they, after having had sexual encounters, found power, in Jesus Christ which they did not have before, to resist the will of a king? This is a death for chastity (at least among the adults who previously accepted intercourse), for sexual dignity (among all of them), and it is more inspiring because they were not virgins.
