I had unprotected sex with my partner and my side of my penis is swollen and my partner and i have no stds?

Penile edema?: This might be the result of minor trauma during sex. If painless and clears up within a day, probably nothing to worry about. See a doctor if it persists, is painful, coninues to enlarge, etc. Even without pain, gonorrhea and chlamydia can do this, and you may still need testing for STDs; you can't be sure based on symptoms alone.

May not be std: This may be a rotation or some type of information. You can see your physician or see a urologist
