Be careful about lying to someone about you having an STD. You might just end up like 71 year old Thomas Redmond of California, who just had his appeal denied, after a jury found him responsible for $6.75 million for infecting his ex-girlfriend with herpes. Yeah, it even sucks to be millionaire sometimes.
Redmond infected his ex-girlfriend with herpes after telling her he's "clean." Long story short, she sues him for $6.7 million dollars for physical damage, emotional distress and medical bills past and current.
