My boyfriend traveled for a work trip for upto a month which means I was alone for as long as he wasn’t around. By the time he came back two days later, he came to see me. I was on my period so I gave him head till he came. Later that night, I noticed some tiny clustered blisters under my lips, painful when touched. It was disgusting. I got antibiotics and all that. I didn’t ask him anything but since then I’ve been avoiding him. He’s been calling and texting but I can’t get myself to look at him.
