My boyfriend uncircumcised penis but on it there are little cuts around it. What is it?

the are a little open, we both think that i have a yeast infection but idk if that will cause it i always make appointments for the gyno doctor but something always comes up. but he says the bother him, this happened like maybe 3 days ago when we have sex he says when he puts it in that when it hurts.

Okay, I'm a little confused. First if you have a yeast infection, you should be examined a doctor to make sure that's what it is, and provided the proper treatment. These are some of the common symptoms with a yeast infection:

"Symptoms of yeast infections can include swollen, red, tender, itching vaginal lips and surrounding skin. Often there is a whitish, clumpy "curdy" vaginal discharge (resembling lumps of cottage cheese). The odor may be unpleasant. For women with recurrent yeast infections, the symptoms tend to flare at the same time during each menstrual cycle. Sometimes women have burning with urination. Intercourse may be painful. Some women complain of vaginal dryness."

Now let me see if I understand you right. He has the small cuts on his penis, is that right? And when he enters, he hurts, or you hurt?

If the cuts are on him and are not healing then he needs to be seen by his doctor to determine why and also why they are there.

If the cuts are on you, then the same thing applies, and you can mention those to the doctor when you see him about the suspected yeast infection.

Any open cuts on the body invite infection so those that are not healing need to be examined by a doctor.  I hope I'm doing better in answering now. :)
