I recently masturbated and when i ejaculated a girl put her mouth over the head of my penis for a few seconds, is this a risk for chlamydia or another sti?? i don't know her sexual history, was a week ago, now i feel the need to urinate more frequent?

While it possible to transmit Sexually Transmitted Infections (STI) through oral sex, it is much more likely to be transmitted by vaginal or anal intercourse. If you are concerned for STI, see your doctor and ask to get tested. Prevent STIs through safe-sex practices using condoms consistently. Thank you for using HealthTap for your health questions!
