Don't see anything wrong with the bisexual label. And re: your statement ~ harbour some guilt when...they succumb to...it. I am reminded of a spoof of Penthouse magazine that was in the old school National Lampoon. It was a magazine called 'RePenthouse' with a scantily clad couple on the cover, saying their evening prayers (presumably Christian, probably Catholic wife sitting on bed; hands clasped, looking upward and husband kneeling). And the blurb/slogan on the cover read; "Feeling good, about feeling bad, about feeling good."
The whole purpose of the bisexual designation was to acknowledge this middle ground between gay & strait. Ironically, many gays & lesbians seemed, at least initially, if not continuously, to ostracise this group more than heterosexuals do. And, by the way, there is apparently a gaggle of ultra-conservative (read, insane) bishops who want to outlaw any and all forms of contraception. And that would definitely include continued existence of this and any other so-called 'dirty' websites. Talk about a flat earth society! I'm not suggesting formation of a cuckold lifestyle crusade a la gay pride, but the nutcases, all too often, have the ear of law~makers (and I use that term loosely). The freedoms that remain after Homeland Security are still tenuous and not guaranteed unless we are vigilant in keeping them.
Sorry, I interjected politics into sex talk...that was in bad taste wasn't it?
