I haven't come to that conclusion based only on what I read on the internet. I came to that conclusion from observations and discussion in my life experiences, from relationship experiences and friendship experiences over time. Female friends have told me that a lot of straight girls pretend to be bisexual...because they think guys will find them hotter..you know, many straight guys like lesbian porn, etc. Some people claim they're bisexual to look "cool". And I have gay friends who told their family that they were bisexual because that's more accepted than fully coming out as gay.
