[|Human|] Hi ive been having discomfort sometime during and also after sex on my penis. My symptoms are swelling little redness and a little pain just underneath the head of my penis. My question is what causes it and how can I stop it from happening. Thanks in advance.
[|AI|]  Hello, Welcome to Chat Doctor .com, swelling with redness and pain underneath head of penis just after sex is suggestive of having an infection around penis. Most probable infection type seems to be genital herpes from your descriptions of complaints that you have provided. Genital herpes is contracted by urogenital route by means of unprotected sexual intercourse. Its manifestations include red colored painful lesions around genital mucus membranes, vesicles, erosion, burning sensations, dysuria, painful coitus. Treatment includes antiviral medications such as acyclovir for 5-7 days, however chances of recurrence is very high. Precaution includes maintaining genital hygiene, avoiding sexual intercourse for about 2 weeks tills lesions heals, avoiding unprotected sexual intercourse. Also try to seek an opinion from meteorologist before starting treatment. Thank you.
