Five months ago I treated with metrogel for bv. Since that time almost everytime I have sex w/my boyfriend he gets an irritation on the top of the shaft of his penis. When we use a condom, he does not get the irritation. My gyno says that there is nothing wrong with me but I definitely think that there is something wrong with me and that I am causing my boyfriend this irritation. Has anyone else had any similar experiences? Can anyone offer any advice?
