Fissures? Wounds? Help?

Silvia

I’m 22 years old. No babies, no pregnancies, just a boyfriend who like to suck on my nipples. A few days ago they got irritated and began to open? I have wounds on my areolas. I’ve been applying lanolin and trying to keep them moist. Please help me? Has anyone had this? I can’t afford health insurance and we have safe sex. How do I heal these faster or at all? As far as I know they aren’t infected as I’ve kept them fairly clean. The yellow is from the lanolin.
