My boyfriend and I have both been tested and we're both STD HIV negative. I started having discharge that developed an odor so my gyno diagnosed me with vaginal vaginosis. Took the antibiotics and I'm good. My boyfriend now is saying his penis itches after everytime we have sex. His doctor has diagnosed him with folliculitis. Our sex life is pretty intense and extremely consistent. How can we prevent him from continuing to get that everything we have sex?
