Hi, Hopefully You Can Help Me Understand What This Is:

Hi, hopefully you can help me understand what this is: about four days ago i felt some discomfort on my labia minora(the part closes to my clitioris). when i examined myself i found that there were small bumps(about three or four) that looked like they had blood inside, they are also itchy sometimes when they come in contact with my clothing, but for the most part, they don't hurt.(side note: i am slightly sexually active; i have received oral, but my partner states that he is in good health) Please help me know what this is and if I should be more concerned.
