Not really a DP or a DH, but a guy I had a brief (not quite two months) relationship with:
Farting loudly whenever he felt like it - even when out with friends, because it was 'unhealthy to keep it in'.
While invited to dinner with his friends, who had a tiny flat, going for a massive, stinky poo in their toilet, leaving the door wide open afterwards, and making the flat reek - he hadn't bothered to flush the loo!
Sweating like a pig and stinking, because he 'didn't believe' in 'unnatural things like deodorants, anti-perspirants
Telling me eventually that he had genital herpes!
Why did I stick it out for nearly two months? Because he wailed and whined that he couldn't promise he wouldn't do something 'stupid' if I rejected him. I took the risk and dumped him nonetheless. He's still alive and kicking (and sweating and stinking and farting ... )
