My husband recently went on a business trip to France. After he came back, I was doing the family washing and I noticed some rather odd stains inside his pants. Also, he has complained of pain in passing urine. Could he have picked up some infection? And could he give it to me?

Stains on the inside of the front of the underpants suggest a discharge.

The combination of a discharge plus pain in passing urine raises the suspicion your husband may have got either gonorrhoea or urethritis. Both of these are sexually transmitted, so I'm afraid you could catch them from him.

So I reckon it's time you two had a frank talk together, probably followed by a visit to the genito-urinary clinic for you both.
