<s>[INST] Hi,I am a 30 year old male. It feels like my foreskin is shrinking. I don't have a phimotic ring as far as I can tell or feel.Everytime I have sex or masturbate it gets tighter afterwards, and the best description I can give is that it "feels like my penis can't fit in its skin". The tightness is only in the area of the ridged band / frenar band. And I can see the veins more clearly because the tightening applies pressure I guess.Is it phimosis even though I can easily fully retract my foreskin and can almost easily pull it back over the glans?Please help me. My doctor said it was yeast and gave me clotrimazol creme. That is over a month ago and I have stopped applying the creme.Thank you. [/INST] HelloI share your concern This could be phimosis or paraphimosis Since I can't physically examine you to get more clues so I would advise you to consult a general surgeon for physical examination and establishment of a diagnosisYou may require circumcision as a definitive treatment.Hope this answers your question.Please feel free to ask for further clarificationBest wishes </s>
