RECURRENT YEAST AND BV

HELP!! It has been a year now and I have seen 3 gyno’s, tried boric acid, probiotics, every thing in the book and I cannot stop getting yeast infections and BV. It started when I met my bf now so I think it has to do with sex. (he is not cumming inside of me) is there anything or any medication that someone has used that helped stop them?! I am desperate!! nothing at all is working. Should my bf go to a doctor too? my gyno’s seem to think no, but the internet is suggesting otherwise. PLEASE HELP!!!
