Hi Chris, The diseases you mentioned in your query are all sexually transmitted diseases. Yeast infection or candidiasis is afungal infection which is associated with thick, white curdy discharge and could be foul smelling Herpes infection is a viral infection which presents as fluid filled blebs,which are painful and itchy. These vesicles or blebs break to form small ulcers which heal leaving no scar Warts are also caused by a virus called human papilloma virus and usually do not have any symptoms I hope I have sufficiently differenciated the different infections you had doubts about. I appreciate the fact that both you and your partner had a STD screen test.
