hello doctor, make about 2 weeks ago I was with my boyfriend having sex and told me he had a very bad smell in my vagina, I realized right then also, embarrassing but it also happened, I went to walgreens and buy treatment for 7 days (clotrimazole) did treatment after 7 days returned to have sex all been fine and doing well without problems but 3 days ago the problem says that the smell is coming back, I do not know what I do not feel odor before sex should I do?
