I've been dating a man for over 3 years, he has fungus on his back. I often wondered if it could be in his blood and body fluids like semen and if it may be harmful for me. I seem to have a what feels like swollen tounge after oral. He indicated that he had been told by a doctor that he has a condition with his scrotum which would require surgery. He mentioned that there's overage or problems with to much in him and he does have very large testicals, which I've never seen any as big as his. Is this a risk factor to me, can this be somewhat sexually transmitted, or before he did do hard drugs.
