A 40-year-old man in Sweden received life-threatening injuries after being stabbed in the lung by his 28-year-old Russian girlfriend.

The couple were staying at the man's apartment in northern Sweden when they got into a heated argument about their relationship.

The 40-year-old says that his girlfriend was disappointed with the quality of their bedroom activies that evening ...

...so she plunged a knife into his guts... Wow....

This poor guy's life is about to get reeeeaaalllly interesting. If he didn't have performance anxiety before -- he's sure have it now.

Imagine forever living in fear that if you don't take care of business in the bedroom that your woman is going to pull a cleaver out of her purse and go Norman Bates on you. That's enough to make any guy wilt under the pressure.
