A British man is suing a woman he went on a date with after being left with a “virus for life” as a result of a kiss.

Martin Conway, says he contracted a cold sore from the woman.

Now he is demanding a payout of over $150,000, stating she failed to inform him she had the herpes simplex virus when she had a “moral and ethical and legal duty” to do so.

Several days after the date Martin says he became ill, developing flu-like symptoms and mouth ulcers.

As a result, he claims it has stopped him from pursuing his dream job as a lawyer and left him too scared to leave his home.
