Much appreciated Kato.
My view on this predicament is this -
If it really is rape as in you cannot stop it then no it doesn't make you gay. Would it be humiliating, especially if word got out? Of course. But rape is defined as involuntary so if ladyboy really did force it in your back door then it's not gay.
If you let it happen where as you could stop it and then screamed rape now that's teh guey imo.
