i had oral and vaginal sex with a girl a few days ago. i did use a condom. ive noticed some bumps on my inner lip in my mouth. they are the same color as my lip and arent really scattered around too much. they arent too big and when i spread my lip out they seem a little more noticeable. they could be just natural and i am just worrying for no reason. is this just a normal thing or is there anything i need to worry about?
