The Mainichi Daily News, my breakfast read, reports that vaginal ejaculation disorder affects 70% of Japanese males. Men with the condition can’t decorate the warm room, having to finish by hand. Or kick the cat (which isn’t a metaphor but could be). Supposedly it’s a byproduct of masturbatory techniques which don’t feel like a vagina.
So that’s all of them then.
I suspect the article is just a link-bait/poor-research pie - but without that what would be left on the internet?
NB: I have no idea if the accompanying illustration, reposted here, is an ad or a cover photo. I don’t speak Mainichi.
