Hi my son has a sensation of wetness at the head of his penis for the past 5 weeks. He has had an sti check which is negative, has also been treated for thrush, but still has this wet feeling, although there is no discharge he has become extremely anxious. He has been under a lot of stress of late, his marriage failing, and also trying to sell his house and living back home with us his parents. He is 28 years old. Any suggestions please? Thank you.
