My boyfriend was diagnosed with what his doctor called a rare form of strep found in the throat, vagina, and GI tract. He works from home and I am the only person he s been in contact with recently. I am prone to strep but have not been sick in quite some time. He recently preformed oral sex on me is it possible he contracted it that way. If so is there a treatment to prevent this happening again with out curbing our activities? Or is this going to be something I am going to have to worry about all the time. I ve never had this issue befor.
