its about my boyfriend

i went to give him oral sex after he had had a shower, everything was fine until i pulled back his foreskin. There were white lumps and what looked like a piece of toilet tissue, im guessing they were dried semen, and sometimes it smells of cheese, but then i noticed the smell, it smelt of poo. do u think he has been putting it somewhere he shudnt have, needless to say i didnt carry on, but could there be something wrong or am i just being a bit paranoid about his cleanliness?
