Welp I definitely do not want women being raped, and I also do not want men falsely accused of rape, and that happens.
Honestly I think anyone making false accusations of anything should be made to serve the same amount of time as the person they were trying to frame would have of convicted.
If this move helps resolve either of those situations, then I am definitely for it.

Now, the argument could be made that it was consensual. I would say that you should keep your pecker in your pants until you are married.
Your proof it was consensual is that marriage certificate.
