Thank you for asking. I can  understand your concern. Normally one should be able to retract the foreskin back easily. In case of foreskin being constructed or tighter, there may be difficulties with sliding foreskin back and forth during sex or masturbation. It may cause a painful intercourse or discomfort while sex. I is required that you must get the condition assessed by a surgeon as he happens to be the expert in such matters. After a detailed assessment and examination a condition can be established and management can be decided accordingly.
