I get so confused about this casual oral sex thing. I have had all kinds of advice and read medical journals. There are many more STD's than HIV --Herpes, and many more+++. I really don't know the right answer! So for a first time casual bj, should I expect my partner to use a condom--same would apply for me. ( Have not been in the situation for a long time as I had a regular partner for years and years.) What say you?? Journals have said both Yes and No That is as clear as mud!
