Hi there, i have a strange small red spot on

Patient: Hi there, i have a strange small red spot on my vagina (it looks like a pimpel). I am sexually active but me and my boyfriend are safe. We were eachothers first so i dont think its a STI or a STD.. At the start of the realationship we used condoms, but i went on the implant, and we decided we liked the feeling without them… Im just quite worried, whats wrong with me?

Doctor:
