You do not need to be bisexual to post here and be welcomed. Indeed, several
of the regular posters to soc.bi are straight; some others are lesbian or gay.
However, if you are straight and post here then there is no need to mention
that you are straight in every single posting. By all means mention your
sexuality if it is of relevance to the discussion at hand, but if you feel a
need to mention that you are straight every time you post then you should ask
yourself why this is so. If you are scared of people thinking that you are
bisexual because you post to soc.bi then perhaps you should refrain from
posting here, or at least post anonymously.
