Hello
Thanks for your query, Based on what you have posted it appears that you have acquired what is called as
Ballano -Posthatis after a rough
oral sex.There are less chances of
STD as you had no vaginal sex.
Please take some antibiotics like Doxycycline along with Anti inflammatory drugs like
Diclofenac twice daily for a week.Observe clean personal hygiene .It should be fine in a week.
