Just recently me and my boyfirend had unprotected sex, while I was on my period. I washed right after, and since he had no blood on him he waited until the next morning. While he was washing with the soap he began to masturbate. Afterwards he went to use the bathroom. He explained to me that he got a small burning sensation before, durning and after he urinated, and a yellowish/whitish pre-cum came out afterwards also. When he masturbates he's okae, but he feels the burming sensation wne he cums also. Do u think that he could possibly have a UTI or a STD? I don't experince any of these problems.
