Can I ask if you had oral sex with your wife, or was it another woman? If it was your wife and she does not have herpes then it's perfectly safe to have oral sex.
If it was with another woman and you don't know her sexual history then she could have herpes and could have given it to you.
Where is the sore and bumps on your body? I'm asking because if they're on the trunk of your body it might be shingles.
