I find really tiny bumps on my lips after oral sex. I thought it was herpes, but they do not look or sound like any description of herpes or even fordyce bumps, they are the same color as my lips and are extremely tiny with the biggest maype being the size of a pen. I thought it was dehydration bumps as it matched the description and it want away in a week, but now they have returned, more of them and with no dehydration or sex I wonder what they are. I do not use any chapstick or burts bees wax or anything on my lips. they do not itch or burn, I only notice them since my lips feel bumpy. Mostly on my bottom lip and inner bottom lip. I used to get a similar reaction in the woods when I cam in contact with poison ivy. but it would go away. I do not know if they are related or if my partner has transferred some problem to me-which she insists she hasn't.
