After having sex with my partner, one side of my penis swelled up. There's no pain, but it itches a bit. Is this normal after sex, and should I be doing anything about it?
A swollen penis after intercourse, accompanied by itching but no pain, can be caused by an allergic reaction to latex condoms, lubricants, or spermicides, or by a skin condition like contact dermatitis; to alleviate symptoms, apply cool compresses, avoid scratching, and use antihistamine creams or hydrocortisone cream; however, if the swelling persists or worsens, or if you experience difficulty urinating, increased redness, or pain, consult a healthcare provider or a urologist for proper evaluation and guidance.
