I'm 24 year male. Since last year I'm facing problem of getting erection sometimes while talking on fine or roaming with girlfriend. I also get watery, transparent,sticky discharge which is different from sperm after sometime of continuous erection. This happens even if we talk normally or even when there is no sexual thought in my mind. One more thing is that it happens only in case of talking or rooming with gf. I'm feared if this is pathological condition of PE, if it is so which type of doctor should I consult?
