Gang rapes are not implausible; however, this story is.
Let's look at some of the facts in point form, and I will add in my commentary on each afterwards.
- man claims to have been kidnapped at gunpoint from a street in a medium-sized city
I find it strange that there were absolutely zero eyewitnesses. Although it doesn't say what time of day it occurred, one could assume that there would be at least SOMEBODY to corroborate something like that.
- he then claims to have been unable to become aroused when the three women were groping his penis
Really? REALLY? I mean, I don't care if you don't like women, or if they were ugly - it's not a conscious response to stimuli that causes an erection. This is why quadriplegics like Christopher Reeve were able to get erections (he talked all about it in one of his documentaries!) But okay, let's take this one at face value. That still doesn't explain:
- afterwards, he was administered an 'unknown substance' which quickly gave him an erection
I've tried viagra (I was curious, so I got a freebie - the wife wasn't complaining), and it doesn't work that fast. Nor does cialis (no experience here, but the documentation says it's the same time, about 60-90 minutes for onset.) It is not especially water soluble either, so I find the alleged method of forced administration highly suspicious, because in theory it should not work. There are no other known substances capable of doing what is suggested, either.
- he was then allegedly raped individually by each of the 3 kidnappers, who collected his semen in a sandwich baggie or something
Come on. So not only did this guy supposedly get an instant boner from a drug whose main complaint is "It takes too long to take effect", but it eliminated the refractory period (the time between ejaculation and another erection), which is not congruent with a) any 33 year old man's normal sexual abilities, I don't care what they say (and hey, I'm also a 33 year old man, so I am a great basis for comparison!), and b) not how viagra works - again, I'm speaking from experience here. It just makes you hard - once you fire the torpedoes (or however you want to phrase it), you still take the same time to 'reload'. But that brings me to an entirely different point too; apparently, defying all logic, this guy literally came buckets, because they all took turns 'milking' him allegedly.
I mean, there are other issues I have with the story; like why 3 women driving a BMW in South Africa (meaning, they had money) had to resort to kidnapping a stranger at gunpoint to get a bag of jizz, when really, all they had to do was ask someone.
This story just doesn't hold up to scrutiny. There's no reason this would have happened.
