i did go to the doctor not to recently ago but the last girl i had sex with, it was just all oral action. i believe the 6th or 7th i had felt my lip form like 2 almost blisters like lesions but instead of being blisters they arent in multiple its 2 dark colored spots with flat line microcuts in those two patches and in those patches it felt like a wettish burn, i didnt give it much mind since i ruled it out as windburn and i was biting my lips through the winds and my whole bottom and top lips were severely dry from the 5th until now. about the beginning of the month, my lips were perfectly fine didnt feel anything but just irritation from licking and biting through the wind. on the dates stated a day after one of those 2, i studied closer and saw flat open lines(I take that from biting and grinding my bottom teeth to my lip), and my bottom felt the same way but nothing happened to my bottom just my top. where these lesions are my lips are partly black already so, where these "cuts" are at they are healing and scabbing already&my bottom&top lip besides where these remaining cuts are are back to normal.....please help me understand what this is, i would have thought that if i had anything of that sort up top since it was back to back oral between both parties i would have the same on my penis but i havent had and hope that i will never have to go through such worry on my penis......is this severe windburn im experiencing or do i really gotta go back to the doctors.....and the girl i had oral with was in January and all the way up until now i didnt notice anything like such....also where the cuts reside in the patches the patches almost resemble everywhere else on my lips are they where just flaky and felt like sandpaper lol there wasnt no warmth really and the patches did not itch......
